sTec, Inc., Santa Ana, CA, has been assigned a patent (8,484,519) developed by Anthony D. Weathers,Richard D. Barndt and Xinde Hu, San Diego, CA, for an "optimal programming levels for LDPC."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "The subject disclosure describes a method for reducing a sector error rate in a flash memory device, the method comprising, identifying a first program verify level having a first value, selecting an adjustment value for the first program verify level and programming the adjustment value to the first program verify level to replace the first value and to shift a first programming distribution associated with the first program verify level, wherein the shift in the first programming distribution is associated with a decrease in a sector error rate, wherein the shift in the first programming distribution is associated with an increase in a bit error rate. A flash storage device and computer-readable media are also provided."
The patent application was filed on July 19, 2012 (13/553,707).
Flash storage device with flexible data format
sTec, Inc., Santa Ana, CA, has been assigned a patent (8,510,497) developed by Mark Moshayedi, Newport Coast, CA, and Seyed Jalal Sadr, Irvine, CA, for a "flash storage device with flexible data format."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A flash storage device includes a flash storage for storing data and a controller for receiving a command containing data and selecting a sector size for the data. The controller allocates the data among data sectors having the sector size and writes the data sectors to the flash storage. In some embodiments, the controller generates system data and stores the system data in the data sectors or a system sector, or both."
