Document Type and Number:
WIPO Patent Application WO/2020/173192
Kind Code:
A1
Abstract:
The subject disclosure relates to a universal flash storage memory module, a controller and an electronic device with advanced turbo write buffer and method for operating the memory module. The Universal Flash Storage (UFS) memory module comprises an input/output interface including: a clock pin for receiving a reference clock signal from a host; a pair of differential input pins for receiving data from the host; and a pair of differential output pins for transmitting data to the host; a flash memory including: a write buffer portion; and a normal storage portion having a plurality of logic units; and a controller including: 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 indicating the UFS memory module is in a shared buffer mode or an advanced mode; wherein if the third register indicates whether the UFS memory module is in the shared buffer mode, the write buffer portion only includes a first shared buffer area; and if the third register indicates the UFS memory module is in the advanced mode, the write buffer portion includes at least one dedicated buffer area, each dedicated buffer area corresponding to one of the plurality of logic units.
