METHOD, APPARATUS AND SYSTEM FOR TORN WRITE MITIGATION

摘要

PROBLEM TO BE SOLVED: To provide a method, apparatus and system for torn write mitigation.SOLUTION: Torn write mitigation circuitry determines if a write operation to a memory 120 is in progress at or about a time of power loss. In response to the write operation to the memory 120 being in progress at or about the time of the power loss, the torn write mitigation circuitry causes torn write data and metadata to be stored in a non-volatile cache 140. The torn write data includes data left in a degraded or uncorrectable state as a result of the power loss. The metadata describes the torn write data.
