Embodiment Construction

[0045] In order to solve the problem of low transmission rate of the existing flash memory, the present invention provides a Nandflash command processing method. The present invention divides the read and write commands of the Nandflash flash memory into several micro-commands, so that multiple micro-commands can be executed in parallel. Thereby, the read and write performance of the flash memory is improved, the utilization rate of the flash memory is improved, and the idle time of the flash memory is reduced. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention, but not to limit the present invention.

[0046] The first embodiment of the present invention provides a Nandflash command processing method, see figure 1 , the method includes:

[0047] S101. Receive a read or write command...

Abstract

The invention discloses a Nandflash command processing method, device, terminal and computer-readable storage medium. The invention splits the read and write commands of the Nandflash flash memory into several microcommands, so that multiple microcommands can be executed in parallel, thereby improving the performance of the flash memory. Read and write performance, improve the utilization of flash memory, reduce the idle time of flash memory, and thus solve the problem of low transfer rate of existing flash memory.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a Nandflash command processing method, device, terminal and computer-readable storage medium. Background technique [0002] With the continuous progress of communication and computing, people have put forward higher requirements for the transmission rate of flash memory. The operation of existing flash memory is basically serial. If you want to read the data in the flash memory, you need to issue the Lc command first, then Waiting for the flash memory data to be ready, and then reading the data from the flash memory, this operation will cause a lot of unnecessary waiting time, limit the performance of the read operation, and ultimately limit the improvement of the flash memory transfer rate. SUMMARY OF THE INVENTION [0003] The present invention provides a Nandflash command processing method, device, terminal and computer-readable storage medium to solve the pro...
