System and method for handling a power supply interruption in a non-volatile memory

摘要

A system for handling a power supply interruption in a non-volatile memory (10) includes a status indicator set (20) for each sector (16) of a non-volatile memory array (14). The status indicator set (20) is operable to indicate a status for the sector (16) and is independently erasable from the sector (16). A state machine (30) is operable to perform operations on the sectors (16). The state machine (30) is also operable to adjust the status indicator set (20) for a sector (16) prior to performing an operation on the sector (16) to indicate an interruption status and to adjust the status indicator set (20) for the sector (16) after completing the operation to indicate a completed status. <IMAGE>
