Abstract
A Universal Flash Storage (UFS) memory module including an input/output interface, a flash memory and a controller, and a method for operating a UFS memory module are disclosed. 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. 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.
