UNIVERSAL FLASH STORAGE MEMORY MODULE, CONTROLLER AND ELECTRONIC DEVICE WITH ADVANCED TURBO WRITE BUFFER AND METHOD FOR OPERATING THE MEMORY MODULE

摘要

The present disclosure provides a Universal Flash Storage (UFS) memory module including an input/output interface, a flash memory, and a controller. The flash memory includes: a write buffer portion; and a normal storage portion having a plurality of logic units. The controller includes: a processor; a first register indicating a maximum size of the write buffer portion; a second register indicating an available size of the write buffer portion; and a third register. If the third register indicates the UFS memory module is in a shared buffer mode, the write buffer portion only includes a first shared buffer area. If the third register indicates the UFS memory module is in an advanced mode, the write buffer portion includes at least one dedicated buffer area, each corresponding to one of the plurality of logic units. The present disclosure also provides a controller, an electronic device and a method for operating a UFS memory module.
