Wear leveling in solid-state device
sTec, Inc., Santa Ana, CA, has been assigned a patent (8,453,021) developed by Mark Moshayedi, Newport Coast, CA, and Seyed Jalal Sadr, Irvine, CA, for a "wear leveling in solid-state device."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A flash storage device performs wear-leveling by tracking data errors that occur when dynamic data is read from a storage block of the flash storage device and moving the dynamic data to an available storage block of the flash storage device. Additionally, the flash storage device identifies a storage block containing static data and moves the static data to the storage block previously containing the dynamic data."

The patent application was filed on Aug. 28, 2012 (13/597,158).

Interleaved flash storage system and method
sTec, Inc., Santa Ana, CA, has been assigned a patent (8,437,190) developed by Mark Moshayedi, Newport Coast, CA, and Seyed Jalal Sadr, Irvine, CA, for an "interleaved flash storage system and method."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A flash storage system accesses data interleaved among flash storage devices. The flash storage system receives a data block including data portions, stores the data portions in a data buffer, and initiates data transfers for asynchronously writing the data portions into storage blocks interleaved among the flash storage devices. Additionally, the flash storage system may asynchronously read data portions of a data block interleaved among the storage blocks, store the data portions in the data buffer, and access the data portions from the data buffer."

The patent application was filed on Nov. 4, 2011 (13/289,966)
