Abstract

The invention provides an instantaneous power failure recovery processing method. The method is executed by a processing unit of the electronic device. The method comprises the following steps: 1, ; and after instant power failure of the electronic device is detected, the flash memory interface is driven to write the data transmitted by the main device into the pseudo-single-layer type unit blocksof a plurality of logic unit numbers through a plurality of channels in a single-layer type unit mode, so that the data of the dynamic random access memory can be written into the pseudo-single-layertype unit blocks as short as possible.

Description

technical field [0001] The invention relates to a data storage device, in particular to a flash memory storage device's instantaneous power failure recovery processing method and device, and a computer-readable storage medium. Background technique [0002] Flash storage devices are generally classified into NOR flash storage devices and NAND flash storage devices. The NOR flash storage device is a random access device. The host (Host) can provide any address to access the NOR flash storage device on the address pin, and obtain the data stored at the address from the data pin of the NOR flash storage device in time. on the data. In contrast, NAND flash storage devices do not have random access, but sequential access. The NAND flash storage device cannot access any random address like the NOR flash storage device. Instead, the host side needs to write the value of the sequence of bytes (Bytes) into the NAND flash storage device to define the request command (Command). Type ...
