Super Talent Assigned Patent

Multi-level controller with smart storage transfer manager
for interleaving multiple single-chip flash memory devices

Super Talent Electronics, San Jose, CA, has been assigned a patent (8,341,332) developed by four co-inventors for a "multi-level controller with smart storage transfer manager for interleaving multiple single-chip flash memory devices."

The co-inventors are Abraham C. Ma, Fremont, CA, David Q. Chow, San Jose, CA, Charles C. Lee, Cupertino, CA, and Frank Yu, Palo Alto, CA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A solid-state disk has a smart storage switch with a smart storage transaction manager that re-orders host commands for accessing downstream single-chip flash-memory devices. Each single-chip flash-memory device has a lower-level controller that converts logical block addresses (LBA) to physical block addresses (PBA) that access flash memory blocks in the single-chip flash-memory device. Wear-leveling and bad block remapping are preformed by each single-chip flash-memory device, and at a higher level by a virtual storage processor in the smart storage switch. Virtual storage bridges between the smart storage transaction manager and the single-chip flash-memory devices bridge LBA transactions over LBA buses to the single-chip flash-memory devices. Data striping and interleaving among multiple channels of the single-chip flash-memory device is controlled at a high level by the smart storage transaction manager, while further interleaving and remapping may be performed within each single-chip flash-memory device."

The patent application was filed on Aug. 5, 2008 (12/186,471).
