Abstract

The utility model provides a solid-state memory system, which comprises a hard disk interface circuit module connected with a host, a memory controller connected with the hard disk interface circuit module through a composite bus, a power supply module, a dynamic random memory module connected with the memory controller through an address bus, at least one flash memory channel, at least one chip-carrier flash memory, and a static memory module connected with the chip-carrier flash memory. The solid-state memory system is set free from the coordination and cooperation working missions with flash media, thus is capable of making every effort to achieve the interface protocol control and the buffer management of DRAMs. In this way, the design difficulty of the memory controller is greatly simplified and the manufacturing period thereof is shortened. The service period of the memory controller is prolonged. Therefore, the solid-state memory system provides support for the effective reduction of both the design and development cost and the production and manufacturing cost. During usage, the chip-carrier flash memory can be flexibly replaced, thereby facilitating the usage of the solid-state memory system for users. The manufacturing cost of the solid-state memory system is also reduced.

Description

A kind of solid-state memory system

Technical field

The utility model relates to a kind of solid-state memory system, particularly a kind of solid-state memory system that adopts sheet to carry flash memories.

Background technology

Solid-state memory does not need read/write head, does not need storage medium to move the storer that (rotation) reads and writes data with respect to disk, CD one class.Solid-state memory is to store data by the on off state of storage chip internal transistor, because solid-state memory do not have read/write head, do not need to rotate, so solid-state memory has little power consumption, advantage that shock resistance is strong.Because cost is higher, how still to use the mechanical type hard disk in the at present big capacity storage; But in the electronic equipment of low capacity, hypervelocity, small size, solid-state memory has very large advantage.

In electronic equipment, the application of solid-state memory is very extensive.BIOS such as computer motherboard is stored in the solid-state memory exactly.In the high-speed data switching equipment, because solid-state memory uses transistor to store data, so under high-frequency, solid-state memory can carry out very fast data exchange.Such as the high-speed cache among internal memory and the CPU.In the equipment of ultra-small volume, solid-state memory is being played the part of critical role.Because solid-state memory is arranged, our electronic equipment just can be done forr a short time.The MP3 player that rubber is big, be so small to have only the big USB flash disk of nail cover and RAM (random access memory) card, these are all in our life of the person of convenience.

Along with the raising of manufacture craft, the number of transistors in the unit area constantly increases, and the data capacity of unit area is also improving constantly.Because the antidetonation of solid-state memory, low-power consumption, characteristic at a high speed, the solid state hard disc of being made by solid-state memory has progressively overcome the shortcoming of early stage low capacity, begins civilian in a large number.But because cost is higher, price is in a high position always.

Nowadays, the big capacity solid-state memory of the second generation comes out, and its structure is the SDRAM device, and each memory module can reach 2Gbits, inputs or outputs data rate and can reach 20Mbps.In fact, be subjected to the constraint of integrated level and price, nowadays big capacity solid-state memory has seldom adopted sram chip as primary storage medium, and has occupied dominant position based on the memory storage of flash memory technology.

Summary of the invention

Based on this, the utility model provides a kind of solid-state memory system.

Concrete technical scheme of the present utility model is as follows:

A kind of solid-state memory system, comprise the dynamic random memory module that the hard-disk interface circuit module that connects with main frame, the memory controller, power module and the employing address bus that adopt compound bus to be connected with described hard-disk interface circuit are connected with described memory controller, comprise that also at least one flash memory passage and at least one sheet carry flash memories, a static store module that is connected with described year flash memories.

Further, described year flash memories is connected with memory controller by described flash memory passage.

Further, described memory controller comprises centre routine storer, DRAM manager and super buffer memory.

Further, be provided with hyperchannel management device in the described memory controller, carry flash memories to described and carry out error check.

The advantage that the utlity model has and beneficial effect are:

This solid-state memory system can make it realize the cache management work of interface protocol control and DRAM to full capacity from coordinating and cooperating the task of flash media to free; Simplify greatly memory controller design difficulty, shortened the manufacturing cycle and prolonged life cycle, provide support for effectively reducing design research and development and manufacturing cost; In use can change sheet flexibly and carry flash memories, make things convenient for the user, also be beneficial to and reduce this cost of goods manifactured.
