IPGoal Microelectronics Assigned Patent

Start-up method for USB flash disk with synchronous flash memory and control

IPGoal Microelectronics, (Sichuan) Co., Ltd., Chengdu, China, has been assigned a patent (9,645,921) developed by Tang, Jian, Chengdu, China, for a “start-up method for USB flash disk with synchronous flash memory and control system.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A start-up method for USB disk with synchronous flash memory includes steps of:,(a) writing test data into a data cache zone of a flash memory according to an initiate read write clock of a flash memory controller, (b) reading the test data to a memory zone of a USB controller, (c) comparing the test data in two memory zones, and recording a comparison result and a phase parameter of read write clock, (d) delaying the initiate read write clock for one-unit delay, and repeating steps, a).about.(d), (e) if the comparison result changes from success to failure, stopping repeat the step, (d), (f) selecting the phase parameter of the read write clock that corresponds to one of the comparison results in an interval with multiple continuous successful comparison results to determine a clock phase for accessing the flash memory, and then starting up the USB flash disk. The method is quick and stable.

The patent application was filed on September 15, 2014 (14/486,464).
