Further, the magnetic memory device has parameter memory that maintains a protected zone used to store protected zone parameters, and an authentication zone used to store authentication parameters, the protection zone parameters and the authentication parameters being associated with the data that requires authentication.

Stripes are formed across a RAID group, data to be written is saved in a non-volatile buffer until enough data for a full strip is received (without any restriction about logical address of data), full stripes are sent and written to paSSDs comprising the RAID group, accordingly the partial stripe read-modify-write is avoided.

Abstract: An unified power management scheme for all the idle subsystems during normal mode of operation and power save mode of operation reduces significant power and time during saving and restoring context of System on a chip (SoC). Power management schemes based on subset of manufacturing tests and high speed non-volatile memory provides transparency and shortest latency of entering and exiting power save mode and as a result providing significant power savings and extending battery life. Due to the shortest logic delays in some phases of logic scan, memory BIST and analog BIST, entry procedure and exit procedures from power save mode consume least amount of time with little overhead due to clock switching and power gating procedures. Any part of SoC that can be tested during manufacture using standard procedures of logic scan, memory BIST, analog BIST and boundary scan will be able to enter and exit power save mode and still retain the state.
