Abstract
A computing system includes at least one functional unit and a magnetic random access memory (MRAM) block coupled to the at least one functional unit. The MRAM block is configured to store a functional state of the at least one functional unit during a power down state of the at least one functional unit.
Claims21
A computing system comprising:
- at least one functional unit;
- and
- a magnetoresistive random access memory (MRAM) block coupled to the at least one functional unit, the MRAM block configured to store a functional state of the at least one functional unit during a power down state of the at least one functional unit.
A method comprising:
- receiving a standby signal requesting one or more functional units of a computing system to enter a standby state;
- responsive to receiving the standby signal, storing at least a portion of a current operational state of the one or more functional units in a magnetic random access memory (MRAM) coupled to the one or more functional units;
- and
- removing power from the one or more functional units after the current operational state is stored.

A system comprising:
- means for receiving a standby signal requesting one or more functional units of a computing system to enter a standby state;
- responsive to the standby signal, means for storing at least a portion of a current operational state of the one or more functional units in a magnetic random access memory (MRAM) coupled to the one or more functional units;
- means for removing power from the one or more functional units after the current operational state is stored;
- means for receiving a wake-up signal requesting the one or more functional units in the standby mode to enter an operating mode;
- responsive to the wake-up signal, means for restoring the power to the one or more functional units in the standby mode;
- and
- means for reinstating the current operational state to the one or more functional units.
