Embodiment Construction

[0052] In the present invention, by establishing a mapping relationship between the storage medium of the flash memory device and at least one cache unit, and according to the mapping relationship, the data to be accessed in the storage medium is cached to the cache unit, and based on the mapping relationship, the cache unit is access. In this way, the service life of the flash memory device is increased.

[0053] figure 1 Shown is a management system structure of a flash memory device in an embodiment of the present invention, the system includes a host 100, a storage medium 200 of a flash memory device, a controller 300, and at least one cache unit 400, wherein:

[0054] An operating system can run on the host 100, which can typically be a personal computer.

[0055] The storage medium 200, connected to the controller 300, is the main storage unit for exchanging data between the flash memory device and the host 100, and it may typically be a flash memory medium.

Abstract

The invention relates to the technical field of semiconductor memory and provides a flash memory device and a management system and a method thereof. The method realizes the management of the flash memory device based on a memory medium and a cache memory unit, and comprises the following steps of: A. establishing mapping relationship between the memory medium and at least one cache memory unit; and B. caching data to be accessed in the memory medium to the cache memory unit based on the mapping relationship, and accessing the cache memory unit based on the mapping relationship. By using the flash memory device and the management system and the method thereof, the service life of the flash memory device can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of semiconductor storage, and more specifically, to a management system and method of a flash memory device and a flash memory device. Background technique [0002] Since the birth of flash memory (Flash Memory) storage media, due to its non-volatile, high storage density, high access speed, small size, low power consumption, low noise, rewritable and shock resistance, etc. It is widely used in flash disk, flash memory card, electronic hard disk (SSD), mobile phone, audio media player (MP3), digital camera, digital video camera, portable media player (PMP), Digital photo frame, digital TV, GPS navigator and other equipment. [0003] Although flash memory has many advantages, compared with storage media such as hard disk and synchronous dynamic random access memory (SDAM), it has certain shortcomings in service life and access speed. Since the writing operation of flash memory must be performed in a...
