Method and device for constructing a high-speed solid state memory disc by using higher-capacity DRAM to join in flash memory medium management

Abstract

A high-speed solid state memory disc device constructed by using a higher-capacity DRAM to join in flash memory medium management is served as the memory device of a computer or a server. The high-speed solid state memory disc device comprises a flash memory medium module (37) and an interface circuit module (31), and particularly comprises higher-capacity dynamic random memory (DRAM) module (35), a DRAM hard disc controller (39) joining in managing flash memory medium, and a double auxiliary electricity management module (38) needed by the DRAM module (35). The DRAM hard disc controller (39) joining in managing the flash memory medium is connected with the DRAM module (35) and the flash memory medium module (37) respectively by address / data buses (32, 33) and connected with the interface circuit module (31) by a composite bus; and the double auxiliary electricity management module (38) is in electric connection with the DRAM hard disc controller (39) joining in managing flash memory medium. The high-speed solid state memory disc device is characterized in that Flash write back is lowered down to the greatest extent and the response speed of the constructed solid state memory disc (SSD) to systems is improved greatly.

Description

technical field [0001] The present invention relates to an erasable programmable read-only memory, in particular to access, addressing or distribution in a memory system or architecture, and in particular to a method for constructing a solid-state storage hard disk by combining DRAM with Flash management and devices. Background technique [0002] With the continuous development of central processing unit (CPU) speed and memory (Memory) speed in the computer field, traditional mechanical hard disks (hard disk drives are hard disk drives in English, used to refer to such hard disks, hereinafter referred to as: HHD) are becoming more and more popular. It has become the bottleneck of data input / output (I / O). Although the continuous improvement of hard disk cache (Cache) technology and interface (PATA, SATA, etc.) technology has greatly improved the speed of HHD, it still cannot meet the further requirements of CPU and bus. Increased I / O speed requirements. [0003] The rapid d...

Problems solved by technology

Since the use of Memory is I / O in continuous space, it is not allowed to participate in the calculation and calibration of bad block area management like hard disks. Therefore, the current application of this B-level product is limited, because it cannot be used effectively like Flash. A certain proportion can effectively complete a certain proportion of cost amortization. At present, DRAM manufacturers have a large number of goods and are still accumulating
