Abstract

Embodiments of the invention provide an information processing method and an electronic device. The information processing method is used for solving the technical problem of relatively low data processing efficiency in a flash memory when instructions are input into an SSD (Solid State Drive). The method comprises: receiving input instructions for a storage device in the electronic device, wherein the input instructions include N write instructions and carry a target logic address, and N is a positive integer; according to the target logic address, obtaining a load index of at least one flash memory region in the storage device; and determining the flash memory regions with the load indexes lower than a preset load index in the at least one flash memory regions, and adjusting operation regions corresponding to the N write instructions to the determined flash memory regions.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to an information processing method and electronic equipment. Background technique [0002] SSD (Solid State Drives, solid state drive) is a hard disk made of solid state electronic storage chip arrays. There is a controller chip in the SSD, which is responsible for data storage and transmission. The SSD is mainly composed of Flash (flash memory) chips. Each Flash chip includes multiple physical pages. The physical pages of the Flash chip are logically divided into different logical blocks. The program running inside the SSD is called firmware. [0003] like figure 1 As shown, the core of the firmware includes three parts, namely a host interface module, an FTL (FlashTranslationLayer, flash translation layer) module, and an NFC (NANDFlashController, NANDFlash controller) module. Wherein, the host interface module is mainly used to obtain from the host interface the read instruct...
