Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Computer technology (Electrical engineering)
Classification: CPC G  Y | IPC G

Claim 0:
1. A system comprising:
an input;
an output; and
a controller coupled to the input and the output, the controller including a non-volatile memory, wherein:
in response to a signal on the input corresponding to a voltage of the system being below a first threshold and greater than zero, wherein the voltage of the system being below the first threshold and greater than zero is a first transition to a low power level, the controller is configured to:
transmit an interrupt on the output; and
transfer data in a volatile memory to the non-volatile memory; and

in response to the signal on the input indicating a voltage of the system being greater than a second threshold, the second threshold greater than the first threshold and representing a power amount sufficient to complete a round trip of a restore operation and a save operation, wherein the voltage of the system being greater than the second threshold is a second transition to a high power level, the controller is configured to transfer the data in the non-volatile memory to the volatile memory.
