Standard method well known to those skilled in the art can be used to manufacture memory storage of the present invention.In one preferred embodiment, according to the standard method known (such as, see Rai-Choudhury (1997) TheHandbookofMicrolithography, Micromachining, andMicrofabrication, SPIEOpticalEngineeringPress; Bard & Faulkner (1997) FundamentalsofMicrofabrication) electrode layer is applied to suitable substrate (such as, silicon dioxide, glass, plastics, pottery etc.).At following and other U.S. Patent number 6,212,093; 6,728,129; 6,451,942; 6,777,516; 6,381,169; 6,208,553; 6,657,884; 6,272,038; 6,484,394; With United States serial 10/040,059; 10/682,868; 10/445,977; 10/834,630; 10/135,220; 10/723,315; 10/456,321; 10/376,865; Describe multiple technologies with US publication 20070123618, by reference it is all combined clearly, the manufacturing technology particularly wherein summarized.

There is the various device and system construction that have benefited from using molecular memory.

By row address reception in N position is received to column address decoder operative memory device to row-address decoder and M bit column address.Row-address decoder is created on the signal in a wordline.Wordline can be included in and drive high current signal to the word line driver circuit in wordline.Because the length that wordline extends across many chip surfaces often, thin conductor, so it needs significant electric current and powerful switch to drive word-line signal.As a result, line driver circuit is often provided with except power supply circuit (not shown) as other logic elements provide the electric power of electrical power for operation to supply.Therefore, word line driver often comprises large assembly, and the speed-sensitive switch of big current often causes noise, increases the weight of the restriction to electric power supply and power governor, and increases the weight of isolating construction.

In a kind of memory array of routine, there are the row (bit line) more than row (wordline), because in renewal rewards theory process, activate every bar wordline and upgrade all memory elements being coupled to this wordline.Therefore, the number of row is fewer, and the time upgrading the cost of all row is fewer.A feature of the present invention be can configure molecular memory element with show tens of, hundreds of, thousands of or effectively, the data hold time significantly grown of the typical capacitor of ratio of the grade of unrestricted second.Therefore, can renewal circulation be performed with more low-frequency order of magnitude or all omit.Therefore, the renewal of the physical layout of the actual influence memory array that can relax is considered, and can realize the array of multiple geometry.Such as, easily can manufacture memory array by more substantial wordline, this will make every bar wordline shorter.As a result, can word line driver circuit be made as less or be eliminated, because need lower electric current to carry out the every bar wordline of high-speed driving.Alternately or additionally, shorter wordline can be driven quickly to improve the read/write access time.Substitute as another, the often row of memory location can be provided with many wordline, to be provided for the mechanism of the various states storing information in each memory location.

Sense amplifier is coupled to every bit lines and operation is coupled to the signal of the state of the memory cell of this bit line to detect instruction on bit line 109, and amplifies this state to suitable logic level signals.In one embodiment, sense amplifier can realize with substantially conventional design, and design conventional like this will operate to detect and to amplify the signal from molecular memory element.Alternately, different from the capacitor of routine, some molecular memory element provide the very different signal of their state of instruction.These different signals can reduce the needs of the sense amplifier logic to routine, because can than the signal be stored in conventional capacitor more easily and be reliably latched into the buffering area of read/write logic from the status signal of molecular memory device.That is, the present invention can provide enough large device to eliminate the needs to sense amplifier.

Read/write logic comprises the circuit for memory storage being placed in read/write status.In read states, the data from molecular array are placed on bit line and (are with or without the operation of sense amplifier), and are caught by buffering area/breech lock (latch) in read/write logic.Which bit lines of selection is active by column address decoder in specific read operation.In write operation, data-signal is urged on the bit line of selection by read/write logic, makes when wordline is activated, and these data will rewrite any data be stored in addressing memory cell.

Renewal rewards theory is substantially similar to read operation; But, the address driving that wordline is driven by refresh circuit (not shown) instead of applied by outside.In renewal rewards theory, sense amplifier, if you are using, drive bit line to the signal level of the current status of instruction memory cell, and this value is automatically written back to memory cell.Different from read operation, at no point in the update process, the state of bit line is not coupled to read/write logic.If the charge retention time of molecule used is less than the operation lifetime of the device of use, such as, for flash memory during the order of magnitude of 10 years, this is just needed to operate.

In one that comprises central processing unit and molecular memory exemplary embedded system, memory bus coupling CPU and molecular memory device are with IA interchange address, data and control signal.Alternatively, embedded system can also comprise the memory of the routine be coupled with memory bus.Conventional memory can comprise random access storage device (such as, DRAM, SRAM, SDRAM etc.) or read-only memory (such as, ROM, EPROM, EEPROM etc.).The memory of these other types can be used for cached data molecular memory device, storage operation system or BIOS file etc.Embedded system can comprise one or more I/O (I/O) interface, and this interface can make CPU and external device (ED) and system communication.I/O interface can by realizations such as serial port, parallel port, prevention at radio-frequency port, optical port, infrared ports.Further, communication can be carried out to use any obtainable agreement (comprising the agreement based on packet) by configuration interface.
