Surgery, especially 4 other devices (such as smart cards, identification tags τm f, and / or can be incorporated into flexible substrates; and / / can be used in high-vibration environments. Months and χ 造成 本 、 、 、 、 、 、 、 The special purpose of the cheap storage is to provide a simple and effective way to store the Du Pu 胄 (4) storage device, and to read (4) Infinity is also written into the Beibei and the words to buy back the information. According to the present invention, there is provided a storable form for storing data, digital video, digital video, etc., comprising: more than one (specifically, a plurality of) memory elements, Each of the memory elements includes a planar magnetic conduit capable of maintaining and conducting a magnetic cut, the planar magnetic conduit forming a dedicated guide, wherein each of the continuous rails has at least one inversion node, and the selection: There may be a plurality of inversion nodes' and in particular there may be a plurality of inversions 2 points 1 under the action of an appropriate applied magnetic field 'magnetic nozzles conducted along the conduit, the direction of magnetization changing at the inversion nodes Direction, specifically, substance The magnetization direction is reversed. The strip guides & are formed in a continuous guide rail. Conventionally, the ducts form a closed loop to include the continuous guide rails. The node, optionally, may have a plurality of inversions, ie, points, and in particular may have a plurality of inversion nodes. According to the mechanism of the following 1310938, the data can be delivered in the closed loop. Sometimes, The magnetic conduit does not constitute an entire closed loop composed of a plurality of inverting nodes; instead, it is a linear link composed of a plurality of inverting nodes, and has a component for transmitting data between the two end points, so the data Still able to circulate around the closed loop, for example, one end of the link includes a beech writer device; the other end of the link includes a f-reading device. :: includes - an additional circuit 'Electronically from the link's resources back to the input of the link. The reversal node of the liver and the like includes the structure and shape of the catheter. After the adaptation of the magnetic field of the appropriate magnetic field (9), the magnetic field in the direction of the magnetic field, the magnetic field of the magnetic field is transmitted. A change will occur. 'The preferred system will produce a change in the direction of magnetization in the direction of magnetization. However, it is necessary to do so that the guides are too a & i t ., _ J to make the direction of the universal domain and the magnetic domain wall change ‘at the same time, no point at any point will be obvious. Therefore, the structural features in the region of the inversion node or the region containing the 3 3 hai reversal node must be capable of causing magnetic domain conduction without any significant violent polarization in the direction of the conduction singularity. The magnetic "direction changes, preferably a substantial inversion change in the magnetization direction. In a preferred embodiment, the inversion section A, ^卽 points include the direction of the magnetization of the inversion node. Inverted. Preferably, the system of Quanjiao has a part of the turning point in the pipe, and the direction of the cutting will not be the same as the original path, and then the direction will change back. In the original Ling ^ ^ ^, in the path taken, therefore there is no direct conduction sub-tower in the deviation. In particular, the deviation from the road including 1310938::2 produces a deviation of 90. Based on the above The deviation from the reason is preferably gradually deviated along the original. The sub- & 軏 as the distance example, 'the reversal node is said to be in the line 1; (7) the structure includes - pendulum. ^ Inward, or a topology equivalent to this structure is better The device according to the invention in each circuit: a plurality of such cycloids. Due to the magnetic conductance f, each magnetic enthalpy uses d Α ^ to include a plurality of cycloids, the cycloids ^ In a sharp manner in the direction of magnetization of the material wall passing therethrough = when the magnetic wall of the nozzle is conducted along the conduit of the present invention, the driving magnetic field of the field acts as the cycloid Preferably, each cycloid has a steering radius 'half the width of the conduit to the ten-seat door'; when the cycloid, the stomach etc. #线: two S domain walls A substantial change in the direction of magnetization can be caused by the cycloidal of X, for example, an inverse of 180. According to the present invention, the addition of the magnetic conduit must be capable of sustaining and conducting the wall of the material under the control of the magnetic field. In general, the magnetic conduit is composed of a continuous continuous track of magnetic material. Therefore, the circuit in the device according to the present invention preferably includes a magnetic circuit, specifically, a (four) substrate. Planar magnetic circuit on. — = This, the data storage device will A plurality of planar magnetic conduits (especially magnetic I/sheng lines) are used. The shape of the closed magnetic circuit is preferably a closed loop composed of a cycloid. The magnetic nanometer technology used in the present invention is The device 1310938 comprises a plurality of plane magnetic nanometer lines and the like, and is formed by a plurality of closed circuits; a plurality of closed loops composed of a cycloid line. "6 Hai and other planar magnetic nanowires have a better width The system is smaller than the melon, and is formed on any suitable substrate.

There should be no special restrictions on technical practice. The improved production technology will be able to further miniaturize the devices used. These lines will be placed on a substrate composed of a thin layer of magnetic material. The thickness of the line must be optimized to achieve the optimum efficiency of the device, and the thickness is generally a function of the width. Specifically, the line thickness is typically one-fortieth the line width. The line thickness is usually not less than 2 nm, preferably not less than 3 nm. In practice, the line thickness cannot be greater than 25nm. Such lines may be fabricated using optical micro-etching techniques, ray ray lithography techniques, microcontact printing techniques, electron beam lithography techniques, shadow mask deposition techniques, or any other suitable method. The lines are constructed of a magnetic material such as a permalloy, or c〇Fe, or any other soft magnetic material. The data storage device using the above-mentioned inversion node must be applied with a suitable magnetic field whose direction is changed (specifically, it should be a cyclically changing magnetic field). The following 1310938 will more accurately describe the operation mode of applying the magnetic field. The method allows the °H reverse node to have a memory function. Providing a plurality of loop arrays each having an 'inverted node' allows the data storage device of the present invention to sequentially store data in a loop-like manner. The data can be written into the apparatus of the present invention indefinitely and read back indefinitely. Unlike the tape storage or magnetic hard disk storage, the present invention does not use the moving parts. Therefore, the data storage device of the present invention can be easily miniaturized and the principle of the present invention can be made very simple in an environment for high vibration, and the manufacturing cost thereof is also relatively low. Furthermore, when the data storage device of the invention is not used, it does not require electricity to maintain the data in its memory. The present invention uses several magnetic conduits such as planar magnetic lines. The planar circuitry is formed on a portion of the substrate, but unlike a microelectronic memory, the substrate is in electronic relationship with the electronic or magnetic operation of the device, which substrate provides substantially only mechanical support. A conventional tantalum substrate can still be used, but since it is not necessary to use the function of the substrate, it is also possible to use materials other than tantalum, such as glass or plastic. Examples of such materials include polyamines such as Kapton, poly(terephthalic acid) 7 t , blowing C* _ vinegar or

The advantages of the plastic substrate are low cost and simple manufacturing method, and J ~ Ami can also provide mechanical elasticity, so that the present invention can be suitably integrated into a clay film (such as a smart card) or a cloth. Unlike a disc, a magnetic tape storage, and a magnetic hard disk storage, since it is not necessary to mechanically access the surface of the present invention, a large number of 1310938 substrates can be stacked on top of each other to form a three-dimensional cubic memory. The surface storage density of the invention is extremely moderate, higher than the tape storage, but lower than the magnetic hard disk storage. Whenever necessary, the rate at which data is read and written is very fast, even higher than the speed of the hard drive. However, the present invention stores data sequentially in a meandering manner, so the access time to a particular data block is relatively low, thus making the present invention still directly replace the main hard disk drive used in the computer. limited. The international patent application pCT7GB01/〇5〇72 is based on the above viewpoints and (4) c〇wbuni〗Welland paper principle, the case is a link of how to use the nano-scale magnetic material points (or nano-scale planar magnetic lines) to construct digital logic circuits. Specifically, the magnetic Ν〇τ gate shown in Fig. 1 of the present invention is explained. Then the line of the research clothes m Yao - ah take the magnetic material of the idle pole: the magnetization direction inside.

Does this mean that? It is limited to the line, which is essentially the direction of magnetization, because of the character representation of Wenzi. The line sweeps through a magnetic, wall, and can change the magnetization. The nature of the magnetic field along the ring means that the wall can be realized near the corner. Even magnetic field 1310938 The NOT gate as described above can be fabricated in accordance with the present invention. For the purpose of the purpose, the shape of the gate is slightly modified, and the shape of FIG. 1 is different from that of FIG. The output of the gate is connected to its input by a magnetic conduit (e.g., a planar magnetic circuit) to form a closed loop. The array of such loops constitutes the apparatus of the present invention in accordance with the preferred embodiment. The apparatus includes planar magnetic nanowires formed in a large closed loop of tandem cycloids to form magnetic The link formed by the N0T gate. The turn of the last NOT gate is fed back to the input end of the first NOT gate by a planar magnetic circuit to form a closed loop to allow the data sequence to be cyclically delivered. When the magnetic binding wall is operated in a proper cyclic operating magnetic field (the above-mentioned magnetic field is as described above, as will be explained in more detail below), the cycloid can be used when conducting through the special line. Acting to conduct the inversion nodes of the walls of the magnetic nozzles. The inverted output will only appear after a half-cycle time delay of the applied magnetic field of the loop, so that each inverted node is like a single back: alpha-hidden early or flip-flop. Therefore, it consists of the cycloids: it has a memory function like a tandem cyclic shift register, and can be used as the data storage device of the present invention. Another aspect of the present invention is that the data storage device provided by the present invention includes one or more of the above device components; and the field driver is provided to provide a controlled magnetic and magnetic Time-varying driving magnetic field. The preferred setting of the device is above all the cycloids of the driving magnetic field, and simultaneously applied to the special loop, all the loops in the beta system. This makes the system unique.

When the clockwise or counterclockwise palm is opposite, the magnetic domain wall 7 has a magnetic field having the same conductance as the corner. However, because: one:: it should be transmitted near the corner of the magnetic circuit. Therefore, in a particular direction, the specific pair of palms will pass through a special t-inner magnetic, and the magic will only need to have a clear signal flow. This result of the direction is in line with the important conditions of any gate logic system. The two stable magnetization directions in the submicro 1310938 m magnetic circuit 1 can provide the essential meaning of representing the logic states of the two kinds of Boolean.

Five people n ^ ^ The monks have been programmed into the installation using a specific sequence of additional magnetic bits: the two are not allowed to loop around the loop.

'The data bit sequence is obtained: Γ: The data is taken from the cyclic magnetic field of the counterclock. =:=: The data is surrounded by the magnetic field in the direction of the counterclockwise The square of the clock can also reverse the direction of the magnetic field to a clockwise direction = the direction of the data cycle is reversed, and begins to wrap around the magnetic loop in a timely manner. RESULTS: Figure 5: The detection sequence of the present invention using lw-bumping closure. Figure 5b11 shows a simple bit 1 circulating around the loop with a repetition period of 13 cycles of the circulating magnetic field. time. The data is written into each loop by the micro-I line above or below the f-plane magnetic circuit carrying the current. To read data from each of the backs, the following method can be used: using a magnetic tunnel junction that is bonded to one of the portions; measuring the magnetic angle of the equiangular complex at the middle of the line The value of the wall resistance of the wall; or the value of the domain wall resistance of the medium and the middle of the N0T gates. An example of such data input/output methods is shown in FIG.

Place a magnetic line segment in the alternating current ^, road Below, and then in the line segment, the current is reduced, the effect can be achieved in the larger facet, the device. As for the large area of the device, the electrode is placed on the substrate with the circuit. This effect can be achieved by the four-electrode 5 electromagnet. The strength of the magnetic field should be sufficient to make the wall push the poem to push the magnetic soil into all directions via the parent NOT gate, but the strength of the cooker It is not large enough to assemble new magnetic walls in the absence of the data entry mechanism of 17 1310938.

For special applications, we can find the best balance between the number of loops and the number of poles in each loop. If the number of loops is v and the number of mothers and roads is very large, it is very easy to integrate them into a package' and the cost is quite low; but if the manufacturing is defective, the single-he Ν〇τ gate If the fault occurs, it may cause the entire fault to occur. This combination also has extremely long data access times because, as far as the specific data block is concerned, on average, we have to wait for a very large number of clock cycles to cycle it to the reading position. If the number of loops is large and the number of gates in each loop is small, there is no need to worry about (4) 'The gate is faulty (because the loop containing the faulty idle pole can be removed from the circuit without serious Reduce the overall storage capacity), and has a very fast access time, but it will have more reading 1310938 points (thus the cost will be higher), ... it is more difficult to package its integrated Sunshine early integrated circuit in. All the drawings in this application: a loop composed of 8 idle poles. However, this is only a schematic diagram. A special feature system in which the mother circuit can contain thousands of gates is not limited to the plane in which the data loop is placed. In the same way as the optical disc, the magnetic tape storage, and the magnetic hard disk storage, it is not necessary to mechanically access the surface of the present invention: as shown in Fig. 8, 'the substrates can be stacked on top of each other, shape Three-dimensional cubic memory. This advantage can achieve very high data progress. When necessary, all of the substrates in the same cube can share the same applied circulating magnetic field to ensure the synchronization state of the layers with each other and to reduce the complexity of the device. The present invention can be designed to input/output a single sequence of data strings, and if necessary, a plurality of loops or a plurality of layers can be used in parallel to store a string of data strings having a width of the extra-bits. Since the access time is extremely low, the present invention is not suitable for replacing the main hard disk drive used in the computer. The present invention can be applied to the following partial cases and other situations: • A pocket type digital music player (e.g., an Mp3 player) can be used as a temporary storage for digital music. This application requires a low-cost, non-volatile, rewritable storage for storing digital information that must be repeatedly played back and forth. If the 2QQnmX (the planar line, the NOT gate can occupy about w area, so a single layer covered by a data link of 1cm2 can provide 12 million bytes of 19 1310938 *. The serial data storage capacity is enough to play 12 hours of CD quality music. The multi-layer stacking method can provide a small number of CD-quality music at a very low cost. The digital camera can be used as a temporary storage digital photo. Use. Currently, this is achieved by flashing electronic memory, but this method is quite expensive and has only a very limited number of overwrite cycles. It can be used for mobile phones, personal notebooks, palmtop computers and smart cards. As a non-volatile offline storage.
