Embodiment Construction

[0042] The application will be described in further detail below in conjunction with the accompanying drawings.

[0043] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0044] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0045] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random acce...

Abstract

The invention aims to provide a Flash chip storage method and equipment. The Flash chip storage method comprises the following steps: determining the memory capacity of a Flash chip and the memory capacity of a residual block; determining a target block according to the memory capacity of the Flash chip and the memory capacity of the residual block, and erasing the target block; equally dividing the erased target block according to the data volume of the written data and the memory capacity of the target block, and determining a target write address of the erased target block; and completing storage processing of the write-in data according to the target write-in address. Therefore, the service life of the Flash chip is effectively prolonged, and erasable blocks are accurately erased.

Description

technical field [0001] The present application relates to the field of computers, in particular to a storage method and device for a Flash chip. Background technique [0002] When a Flash chip writes a large amount of data, it needs to erase the entire block multiple times, thereby reducing the read and write life of the Flash chip, and prematurely causing the device to reach the end of its life cycle. In order to prolong the service life of the equipment, the existing storage methods are as follows: [0003] 1) On the basis of the conventional permanently erased Flash chip memory, a verification mechanism is added to determine the erased block through verification, and then find an unused block again, so that the service life of the device can be extended. Disadvantages If the code space is not enough, or if there is data in the remaining block, the entire block will be erased and there will be a code error; [0004] 2) After erasing a block (block), divide the block into...
