Title: MANAGING SOLID STATE DRIVE DEFECT REDUNDANCIES AT SUB-BLOCK GRANULARITY
Abstract:
Systems, apparatuses and methods may provide for initiating an erase of a block of non-volatile memory in response to an erase command, wherein the block includes a plurality of sub-blocks. Additionally, a failure of the erase with respect to a first subset of the plurality of sub-blocks may be tracked on an individual sub-block basis, wherein the erase is successful with respect to a second subset of the plurality of sub-blocks. In one example, use of the second subset of the plurality of sub-blocks is permitted, whereas use of the first subset of the plurality of sub-blocks is prevented.
