Embodiment Construction

[0027] The central idea of ​​the present invention is to further reduce the size of the solid-state hard disk, save power consumption and enhance the read-write performance of the solid-state hard disk by packaging the controller and the embedded DRAM into the main microcontroller chip.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0029] In order to solve the defects of the solid-state hard disk in the prior art, the embodiment of the present invention provides a solid-state hard disk structure, which uses embedded DRAM (Embedded DRAM, referred to as eDRAM) to replace the traditional DRAM cache chip, and then forms such as figure 2 The SSD structure shown.

[0030] Specifically, such as figure 2 As shown, the solid-state hard disk (specifically NAND-type solid-state hard disk, which can be applied to various mobile terminal devices) m...

Abstract

The invention relates to the technical field of computer information, in particular to a solid state disk structure. A controller and an embedded DRAM (dynamic random access memory) are packaged in a chip of a main microcontroller; on one hand, rapid read and write of data can be realized to the greatest extent with adoption of the technical scheme, power consumption of a solid state disk is reduced to a certain degree, the size of the solid state disk is reduced, and the read-write property of the solid state disk is greatly reinforced; and on the other hand, the technical scheme is completely compatible with an embedded DRAM manufacturing technology and a CMOS (complementary metal oxide semiconductor) logic technology, the embedded DRAM and the controller can be completely integrated to the same chip, the production cost of the solid state disk is reduced, performance improvement of the solid state disk is facilitated, and the structure is better applicable to various mobile terminal devices.

Description

technical field [0001] The invention relates to the technical field of computer information, in particular to a structure of a solid-state hard disk. Background technique [0002] NAND solid-state drives have become the mainstream non-volatile storage technology and are widely used in various fields such as data centers, personal computers, mobile phones, smart terminals, and consumer electronics, and the demand is still growing. The manufacturing process of NAND solid-state drives has also been developed to 10nm, transforming from a two-dimensional manufacturing process to a three-dimensional manufacturing process. Because solid-state drive technology is different from traditional hard drive technology, many emerging memory manufacturers have emerged. Manufacturers only need to buy NAND storage particles, coupled with appropriate control chips, can produce solid-state drives, such as figure 1 shown. The new generation of solid-state drives generally adopt the SATA interfa...
