Flash memory controller, related access method and electronic device

Abstract

The invention discloses a flash memory controller. The flash memory controller comprises an artificial intelligence module and a microprocessor. In operation of the flash memory controller the artificial intelligence module is used for determining a first user behavior mode or a second user behavior mode according to a plurality of access commands from a main device and/or a plurality of parameters of a flash memory module controlled by the flash memory controller, and generating a judgment result according to the first user behavior mode or the second user behavior mode; and when the judgmentresult is the first user behavior mode, the microprocessor adopts a first control strategy to control the flash memory module, and when the judgment result is the second user behavior mode, the microprocessor adopts a second control strategy different from the first control strategy to control the flash memory module.

Description

technical field [0001] The invention relates to a flash memory controller. Background technique [0002] In the current flash memory controller, the control strategy adopted for the flash memory module is set by the engineer according to the pre-assumed user behavior, so as to set related algorithms and parameters. For example, the flash memory controller uses the same garbage collection trigger condition, the same wear leveling operation, and the same trigger mechanism for the read scan operation no matter what the situation is, however, the usage behavior of different users may have different There is a large difference, and the behavior of the same user may also change over time. Therefore, if the same control strategy is used to control the flash memory module, it may not be possible to achieve the optimization of the system performance. [0003] For example, housewives or office workers may spend most of their time surfing the Internet or reading information, so what t...

Problems solved by technology

For example, the flash memory controller uses the same garbage collection trigger condition, the same wear leveling operation, and the same trigger mechanism for the read scan operation no matter what the situation is, however, the usage behavior of different users may have different There are large differences, and the usage behavior of the same user may also change over time. Therefore, if the same control strategy is used to control the flash memory module, it may not be possible to achieve the optimization of system performance.

[0003] For example, housewives or office workers may spend most of their time surfing the Internet or reading information, so what they are looking for is the optimization of the flash memory module's reading behavior; and students may often Will download files or write files, so the comparison pursued is the optimization of the write behavior of the flash memory module
