Abstract
Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, the logic determines an intermediate parity value based on a first parity calculation, and using the intermediate parity value determines a final parity value based on the intermediate parity value and a second parity calculation. Determining the intermediate parity value includes sending a uni-directional command to read an old data value from an address indicated in the uni-directional command, perform an exclusive-or operation on the old data value and a new data value indicated in the uni-directional command to determine the intermediate parity value and store, in the persistent storage media, the intermediate parity value at a location associated to an index indicated in the uni-directional command.
