MediaTek Files Patent

MediaTek, Inc., Hsinchu City, Taiwan filed patent application for "serial flash controller, serial flash memory, and method thereof."

The inventors are Yu-Shan Chou and Jien-Jia Su.

MediaTek Inc. filed the patent application on Sept. 14, 2012. The patent application number is 2684/MUM/2012 A. The international classification number is G06F12/00.

According to the Controller General of Patents, Designs & Trade Marks, "Embodiments of the invention provide a method performed by a serial flash controller and a serial flash memory that are interconnected by a serial clock (SCK) line, a plurality of serial input/output (SIO) lines, and a latch line. The SCK line carries a SCK clock from the serial flash controller to the serial flash memory. Under the method, the serial flash memory synchronously transmits to the serial flash controller data bits through the SIO lines and a memory-generated latch signal through the latch line. The serial flash controller uses the memory-generated latch signal instead of the SCK clock to latch the data bits received through the SIO lines."
