摘要:
A system for moving checksums within memory utilizes a plurality of memory systems and a system manager. A first memory system has a first memory location that is correlated with a checksum indicator. The checksum indicator identifies the memory system that is storing the checksum of the value presently stored at the first location. The system manager dynamically moves the checksum to a destination memory location and updates the checksum indicator such that the checksum indicator identifies the memory system of the destination memory location. While the checksum is being moved, checksum updates may occur to the memory location from which the checksum was moved. Thus, after moving the checksum, the system manager updates the checksum with the value stored at the location from which the checksum was moved. As a result, the checksum stored in the checksum destination location should be sufficiently updated to enable data recovery.
