Latest Patents

Yeh's latest patents include a "Method and apparatus for monitoring non-volatile memory read errors using background media scan." This invention provides a method and apparatus that perform a background media scan (BGMS) with improved efficiency. The disclosed BGMS processes can monitor data retention performance of a large capacity solid state drive (SSD) without significantly increasing scanning overhead by scanning only some sample pages of a memory block. Another significant patent is for "Methods and apparatus for read disturb detection based on logical domain." This invention offers methods and apparatus that monitor and mitigate Read Disturb errors in non-volatile memory (NVM) devices such as NAND flash memories. The disclosed methods determine which logical block addresses (LBAs) in the NVM device are frequently accessed by a host, rather than looking at physical address accesses. The potential Read Disturb errors may then be mitigated by triggering Read Disturb mitigation when the numbers of access of one or more of the frequently accessed LBAs exceeds a predefined number of accesses.
