Description

technical field

[0001] The invention relates to a micro-flash disk, in particular to a micro-flash disk which can ensure the safety of memory data. Background technique

[0002] At present, traditional hard disks are usually accessed mechanically. Therefore, in environments with a lot of vibration or high humidity, the mechanical access method of the disk is prone to problems such as damage or failure of reading and writing. In view of the advantages of high stability, shock resistance, moisture resistance and high transmission speed, flash memory has been used to replace the magnetic disk in the traditional hard disk, and a storage medium called flash disk (Flash Disk) has been developed.

[0003] Such as figure 1 As shown, the micro-flash disk 10 is mainly composed of three major components including an integrated disk electronics (IDE) interface 12 , a control chip 14 and a flash memory 16 . Flash memory has a limited lifetime and usually only guarantees 100,000 writes....
