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

Claim 9:
10. A method comprising:
determining, by a controller, a first voltage below a first threshold and greater than zero;
in response to determining the first voltage below the first threshold and greater than zero, wherein the first voltage is a first transition to a low power level:
transmitting, by the controller, an interrupt; and
transferring, by the controller, data in a volatile memory to a non-volatile memory;

determining, by the controller, a second voltage 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 second voltage is a second transition to a high power level; and
in response to determining the second voltage being greater than the second threshold, transferring, by the controller the data in the non-volatile memory to the volatile memory.
