Embodiment Construction

[0024] Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a management platform for extending memory life of a storage device according to the present invention. As shown in FIG. 1 , the present invention allows users to extend the lifetime of memory through a management platform 10 for extending memory life of a storage device, which mainly includes a memory control unit 14 and a processing unit 16 . The memory control unit 14 is mainly used for reading, writing, formatting and erasing the multiple virtual access units 12 a - 12 c (as shown in FIG. 2A ) in the memory 12 .

[0025] Please refer to FIGS. 2A-2B . FIGS. 2A-2B are schematic views of the memory management method of the present invention. As shown in FIGS. 2A-2B , the memory 12 is mainly composed of a plurality of virtual access units 12a-12c, and a predetermined number of virtual access units (virtual access units) are defined as virtual blocks (virtual blocks) 11a, 11b.

[0026] In order to realize the man...

Abstract

The invention provides a management platform for prolonging memory service life of a storage device, and is mainly used for managing memories (comprising SD, MMC, micoSD and the like) in a storage device. The memory is mainly composed of a plurality of virtual access units, and defines a preset number of the virtual access units as a virtual block. In the management platform for prolonging the memory service life, a memory control unit accumulates operation times of the selected virtual access units during the program operation of the selected virtual access units; and a processing unit determines whether the data which are respectively stored in a plurality of memory units are necessary to be removed from the original virtual access units according to an operation threshold so as to avoid data loss due to damage of the virtual access units.

Description

technical field [0001] The invention relates to a management platform for prolonging the service life of memory, in particular to a management platform for prolonging the service life of memory for storage devices. Background technique [0002] In the current industrial computer embedded system, most of them use flash memory-based CF card, USB DOM (Disk On Module) memory module, SATA DOM (Disk On Module) memory module, IDE SSD (Solid State Disk) solid state hard disk or SATA SSD (SolidState Disk) as its storage medium. [0003] Flash memory is mainly composed of many transistor memory cells, and its data access is through Fowler-Nordheim tunneling to achieve data storage or deletion operations, and there will always be a large amount of current in the data storage The dielectric layer that passes through the floating gate (FG) side of these transistor memory cells is taken. [0004] Because of this, transistor memory cells start to error or fail after a certain number of w...
