Embodiment Construction

[0031] Please refer to figure 1 and figure 2 , figure 1 It is a functional block diagram of the flash memory device 100 according to an embodiment of the present invention. figure 2 for figure 1 A schematic diagram of the physical block 140. The flash memory device 100 includes a flash memory 110 and a controller 150 . The flash memory 110 has a plurality of physical blocks 140, and each physical block 140 has a plurality of flash memory units 142 for storing data. The controller 150 can perform read, erase and program (also called write) operations on the flash memory unit 142 .

[0032] Each physical block 140 can also be divided into a plurality of physical pages, and each physical page has a plurality of flash memory units 142 for storing data. In addition, the physical page that has been written with data must be erased before it can be used to write data again, and the physical block is the smallest unit of erasing, and the physical page is the smallest unit of p...

Abstract

The invention relates to a flash memory device, a driving recorder with the flash memory device and a management method thereof. A controller of the flash memory device detects whether the number of blocks is larger than the preset value or not, so as to determine whether the number of physical blocks in a data area and a standby area is reset or not. The number of the blocks is the number of the physical blocks in the data area which have been replaced by the physical blocks in the standby area, or the number of the physical blocks in the standby area which are used for replacing the physical blocks in the data area. Thus, the health degree of the flash memory device can be evaluated, and a user can be timely informed just before the flash memory device is damaged.

Description

technical field [0001] The present invention relates to a flash memory device, a driving recorder and a management method of the flash memory device, in particular to a flash memory device, a driving recorder and a flash memory device capable of evaluating the health status of its flash memory management method. Background technique [0002] In a general flash memory device, since the flash memory is mainly operated by injecting electrons into or pulling electrons out of its floating gate (floating gate) by a high-voltage electric field, these processes are very important to the flash memory cell. It is a destructive operation. For this reason, conventionally, the program erase (program erase; PE) times of the flash memory is generally used as an indicator for determining the endurance of the flash memory. Most flash memory devices suffer from insufficient product endurance (lifetime). This problem involves the characteristics of the flash memory itself, the architecture ...
