  • Failure logging mechanism to reduce garbage collection time in partially reused bad blocks
    Patent number: 9542286
    Abstract: A memory system logs failures to optimize garbage collection in partial bad blocks that are reused in non-volatile memory. A failure in a primary block may be logged in an inverse global address table. A garbage collection operation can reference the log in order to automatically avoid the failure in the primary block when the primary block is picked as the source block for garbage collection. Likewise, the garbage collection operation may scan only the logged wordlines in the secondary block when the secondary block is picked as the source block for garbage collection.
    Type: Grant
