SK hynix Assigned Patent

SK hynix memory solutions, San Jose, CA, has been assigned a patent (8,516,281) developed by Kwok W. Yeung, and Kin Ming Chan, Milpitas, CA, for an “on demand HDD drive system on a chip power control scheme.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An access instruction associated with accessing a target location in a disk is obtained. A number of units until the target location is accessed is calculated. It is determined whether there is time for the group of logic to transition from a lower power state to an operational state; the determination is based at least in part on the number of units between a current location of a read head associated with the HDD system and the target location which is different from the current location of the read head and a warm up time associated with the group of logic. If it is determined there is time, the group of logic is put into the lower power state.”

The patent application was filed on June 21, 2012 (13/529,980).
