Problems solved by technology

[0003] In the existing technology, the FLASH chips designed by manufacturers are usually general-purpose FLASH, or in order to meet the requirements of different situations, they will design different types of chips, such as low-power FLASH used in wearable devices, computers, etc. High-speed FLASH, etc., and the way that one FLASH corresponds to one mode not only increases the cost of design and testing, but also when the use environment changes, the chip must be replaced, which increases the cost of use and reduces the flexibility of FLASH use

Abstract

The embodiment of the invention discloses a flash memory and a method and a device for switching the working mode of the flash memory. The flash memory has at least two working modes. The flash memoryincludes an instruction obtaining module for obtaining a mode switching instruction for switching the working mode. The parameter adjusting module is configured to adjust the flash memory parameter value according to the mode switching instruction, and control the flash memory to run according to the flash memory parameter value to switch to the operation mode specified by the mode switching instruction. By adopting the technical proposal of the invention, the cost can be reduced and the use flexibility can be increased.

Description

technical field [0001] Embodiments of the present invention relate to flash memory technology, and in particular to a flash memory, a method and a device for switching an operating mode of the flash memory. Background technique [0002] As a non-volatile semiconductor memory, FLASH is favored by various electronic devices. Therefore, different electronic devices have different requirements for FLASH. [0003] In the existing technology, the FLASH chips designed by manufacturers are usually general-purpose FLASH, or in order to meet the requirements of different situations, they will design different types of chips, such as low-power FLASH used in wearable devices, computers, etc. High-speed FLASH, etc., and the way that one FLASH corresponds to one mode not only increases the cost of design and testing, but also when the use environment changes, the chip must be replaced, which increases the cost of use and reduces the flexibility of FLASH use.
