Memory

Abstract

The embodiment of the invention discloses a memory, and the memory comprises a storage module which comprises a plurality of data blocks; a control module, the control module comprises a first pointerand a second pointer; the control module is used for updating the timestamp of the data block corresponding to the ith erasing operation into i when the ith erasing operation is executed, and triggering static loss equalization when it is detected that the timestamp difference between the data block with the smallest timestamp pointed by the first pointer and the data block with the largest timestamp pointed by the second pointer is greater than or equal to a timestamp threshold. According to the embodiment of the invention, the method comprises the steps: carrying out the processing, the maximum timestamp, the minimum timestamp and the timestamp difference thereof can be obtained through the first pointer and the second pointer at any moment; static loss equalization is triggered quickly, the minimum timestamp and the maximum timestamp do not need to be obtained by scanning the erasure times of all blocks every time, all the erasure times of all the blocks do not need to be scanned,and correspondingly, the scanning process does not need to be carried out by consuming time.

Description

technical field [0001] Embodiments of the present invention relate to memory technologies, and in particular, to a memory. Background technique [0002] The eMMC (Embedded Multi Media Card, embedded multimedia) chip is an embedded memory mainly for products such as mobile phones or tablet computers. The eMMC chip integrates a controller that provides a standard interface and manages flash memory, so that mobile phone manufacturers using eMMC chips can focus on other parts of product development and shorten the time to market. [0003] The eMMC chip is mainly composed of a controller and a flash memory particle. Data is stored in the flash memory particle through a write operation, and data is read from the flash memory particle through a read operation. At present, the mainstream flash memory in the market is NAND flash, which has the advantages of small size, large capacity, and fast rewriting speed. It is suitable for storing large amounts of data and has been more and mo...

Problems solved by technology

[0004] However, at present, the number of erasing and writing of each physical block is often recorded through an array, and then the number of erasing and writing of each physical block is compared in each scan. If the difference threshold is exceeded, static wear leveling is triggered. Obviously, the scanning process takes a long time , unable to quickly trigger static wear leveling
