Abstract

The invention discloses an information processing method and an electronic device. The method includes the steps of obtaining operation instruction sets of all N storage units of a storage device, switching and allocating channels for the N storage units on the basis of control sites corresponding to the operation instruction sets of the storage units, and sending instructions to the N storage units through the channels till the instructions in the operation instruction sets are completely sent to the N storage units, wherein in the step of switching and allocating the channels for the N storage units and obtaining the operation instructions of the N storage units through the channels, one channel is allocated for the nth storage unit each time, and the mth group of instructions in the operation instruction set corresponding to the nth storage unit are sent to the nth storage unit.

Description

Technical field [0001] The present invention relates to storage device management technology in the field of information processing, in particular to an information processing method and electronic equipment. Background technique [0002] The chip controller NFC (NAND Flash Controller) is a logic circuit that controls the read and write operations of NAND Flash memory chips, and it often exists in SSD (Solid State Drive) and CPU SoC chips. Due to the complicated interface control timing of NAND Flash, various NAND Flash processes (SLC, MLC, TLC, 3D), and NAND Flash manufacturers using private rather than public command formats, the design of NAND Flsh controllers needs to consider many factors. There are two commonly used design methods: Based on FSM (Finite State Machine), hard-wired circuits are used to achieve control timing. Based on Micro Sequencer, a programmable microcode controller is used to control the timing sequence. However, no matter what kind of controller mentio...
