Data Updating in Non-Volatile Memory

摘要

Various embodiments of the present invention are generally directed to an apparatus and associated method for updating data in a non-volatile memory array. In accordance with some embodiments, a memory block is formed with a plurality of types of memory cell sectors arranged in data pages of a first type and log pages of a second type that can be updated in-place. A first updated sector is written to a first log page while maintaining an outdated sector in an original data page, and overwritten with a second updated sector.
