Solid state hard disc and method for processing its management data

Abstract

This invention discloses a solid state hard disk, it includes: A data interface unit, connects the processing board through the first main line, then the solid state hard disk exchanges data with operating system moving on the processing board through this data interface unit; One memory control unit at least, connects the data interface unit connection through the second main line, and each memory control unit controls one memory slug at least; The managerial data memory cell independent on the memory chip of the solid state hard disk, connects the data interface unit connection through the second main line, to save the managerial data of the memory chip. This invention also discloses correspondingly a method for processing the managerial data of solid state hard disk. According to this invention's hard disk and the management, it may separate the managerial data and the service data and to save, then avoids erasing the managerial data because of misoperation, so enhances the solid state hard disk's reliability.

Description

technical field [0001] The invention relates to the field of communication electronics, in particular to a solid-state hard disk and a method for processing management data in the solid-state hard disk. Background technique [0002] With the development of electronic technology, the operating frequency of the Central Processing Unit (CPU) has increased by 600 times in 20 years, and the capacity of the memory has increased by tens of thousands of times. However, with the explosive growth of data capacity, the bottleneck effect of the data read speed of memory is becoming more and more obvious, and the traditional magnetic recording storage technology has not yet achieved a major breakthrough. In recent years, some manufacturers have begun to actively develop storage technologies and products that can replace magnetic recording, such as solid state disks (Solid State Disk, SSD) based on flash memory (flash). Due to the use of flash storage media, it has no internal mechanical...

AI Technical Summary

Problems solved by technology

The inventor found in the process of realizing the present invention that storing both the management data and business data of the NAND flash in the NAND flash in the prior art will cause the user to mistakenly erase the management data when performing an erase operation on the business data, resulting in SSD is unavailable, making SSD less reliable
