Abstract

The present invention relates to a kind of high speed hard-disk based on Dram, this high speed hard-disk includes to resolve SATA serial line interface and the SATA interface chip of data communication, the control hard disk controlling chip of hard disk operational state, Dram control chip, Dram array and stand-by power supply circuit composition, described SATA interface chip is connected with described hard disk controlling chip, described hard disk controlling chip is connected with described Dram control chip and stand-by power supply circuit the most respectively, and described Dram control chip is then connected with described Dram array.Owing to the access speed of Dram is fast, therefore high speed hard-disk based on the Dram theory of the present invention just can reach the peak velocity of SATA interface, thus the access speed of hard disk is greatly improved.The high speed hard-disk based on Dram realization of the present invention can realize superfast read or write speed, is 100 times of standard machinery hard disk, solid state hard disc 20 times.

Description

A kind of high speed hard-disk based on Dram

[technical field]

The present invention relates to hard disc of computer, particularly to a kind of high speed hard-disk based on Dram.

[background technology]

Along with the development of computer technology, active computer CPU speed is increasingly faster, and internal memory holds Amount and speed are substantially improved.Although hard disc of computer capacity is constantly strengthening, but accesses Speed but slower development.In actual computer uses, hard disk accessed to be become slowly the most really Computer operational efficiency is low, the principal element of the most stuck case.Os starting, beats When opening large software, when running a large amount of disk read-write program, hard disk indication lamp is in frequently flicker Now the occupancy of CPU is the highest, and hard disk becomes the short slab limiting computing power.Although The appearance of solid state hard disc alleviates this problem to a certain extent, but expensive, and service life Shorter, it is impossible to meet the use demand of a large amount of disk read-write.

[summary of the invention]

Present invention seek to address that in the problems referred to above, hard disk is shorter for service life, it is impossible to meet a large amount of magnetic Dish read-write use demand, and provide a kind of be greatly improved access speed based on Dram High speed hard-disk.

For achieving the above object, the invention provides a kind of high speed hard-disk based on Dram, It is characterized in that, this high speed hard-disk includes to resolve SATA serial line interface and data communication SATA interface chip, control the hard disk controlling chip of hard disk operational state, Dram control Chip, Dram array and stand-by power supply circuit composition, described SATA interface chip is with described Hard disk controlling chip connects, and described hard disk controlling chip controls core with described Dram the most respectively Sheet and stand-by power supply circuit connect, described Dram control chip then with described Dram battle array Row connect.

Described Dram array includes the Dram chip of polylith same size.

The favorable attributes of the present invention is, it efficiently solves the problems referred to above.Due to Dram Access speed fast, therefore the high speed hard-disk theory based on Dram of the present invention just can reach The peak velocity of SATA interface, thus the access speed of hard disk is greatly improved.The present invention based on The high speed hard-disk that Dram realizes can realize superfast read or write speed, is standard machinery hard disk 100 times, solid state hard disc 20 times.Because the entity of storage data is internal memory, so not existing The problem in service life.

[accompanying drawing explanation]

Fig. 1 is the structured flowchart of the present invention.

[detailed description of the invention]

The following example is the present invention to be explained further and supplements, and does not constitute the present invention and appoints What limits.

As it is shown in figure 1, the high speed hard-disk based on Dram of the present invention is mainly by SATA interface Chip 1, hard disk controlling chip 2, Dram control chip 3, Dram array 4 and standby Form with power circuit 5.For purposes of illustration only, " hard disk " described in embodiment all refers to this Bright high speed hard-disk based on Dram.

Described SATA interface chip 1 is responsible for SATA serial interface protocol and is resolved and data communication, It can be selected for known SATA interface chip 1, or corresponding by arranging by those skilled in the art Hardware circuit realize.

Described hard disk controlling chip 2 is the major control chip of hard disk, and it is responsible for hard disk operational shape State control, hard disk access protocal and the function such as internal memory operation protocol conversion and data check, it can Select known hard disk controlling chip 2, or by those skilled in the art by corresponding hardware electricity Road realizes.

Described Dram control chip 3 is responsible for the control to described Dram array 4, its Power supply and clock control, reading and writing data, Refresh Data and data including Dram chip 41 The functions such as address mapping.

Described Dram array 4 includes the Dram chip 41 of polylith same size.Described Dram chip 41 can be selected for known Dram chip.

Described stand-by power supply circuit 5 be in order in the case of computer shutdown preserve hard disc data and The extra power supply increased.Described stand-by power supply circuit 5 includes battery and charge and discharge control electricity Road, described battery can be selected for known lithium battery etc., and described charge-discharge control circuit can be according to existing Some charge-discharge control circuits are configured.

As it is shown in figure 1, described SATA interface chip 1 is connected with described hard disk controlling chip 2, Described hard disk controlling chip 2 respectively with described Dram control chip 3 and stand-by power supply circuit 5 connect, and described Dram control chip 3 is connected with described Dram array 4.Thereby, Just the high speed hard-disk based on Dram of the present invention is defined.Be below the present invention based on dynamic The operation principle of the high speed hard-disk of state internal memory:

When its work, described SATA interface chip 1 is by the SATA interface reading and writing data of hard disk Request passes to described hard disk controlling chip 2, and hard disk controlling chip 2 resolves this read-write operation also It is converted into the read-write operation of Dram, thus drives Dram control chip 3, its Rear Dram control chip 3 by control in Dram array 4 one or more dynamically Memory chip 41 completes operation.Computer is when carrying out hard disk write operation, and the flow direction of data is as follows: SATA interface chip 1 converts serial data into parallel data and passes to hard disk controlling chip 2, Hard disk controlling chip 2 increases effect code to data and is sent to Dram control chip 3, dynamic State Memory control chip 3 drives specifies Dram chip 41 to complete data write activity.

When computer is properly functioning, the high speed hard-disk based on Dram of the present invention is by outside The power supply of power supply, i.e. computer is powered, and described stand-by power supply circuit 5 is filled by external power source simultaneously Electricity.Now, in the high speed hard-disk based on Dram of the present invention, all chips are in normal work Make state.

When computer closedown/accident power-off, at the high speed hard-disk based on Dram of the present invention In low power consumption data hold mode；Now powered by described stand-by power supply circuit 5, described SATA Interface chip 1 is closed, and first described hard disk controlling chip 2 controls Dram control Coremaking sheet 3 enters low power consumpting state after entering low power consumpting state.Dram control chip 3 is fitted When turning down Dram voltage, reduce Dram clock and data refreshing frequency so that dynamically Memory array 4 is in lowest power consumption state.

Although being disclosed the present invention by above example, but the scope of the present invention is not Being confined to this, under conditions of without departing from present inventive concept, above each component can use affiliated technology The similar or equivalent element that field personnel understand is replaced.
