Patent ID: 8817569

Claim:
A method of operating a non-volatile memory circuit connected to receive a supply voltage for use in operations performed therein, the method comprising: monitoring by the memory circuit of the voltage level of the voltage supply; while monitoring the voltage level of the voltage supply, determining whether the voltage level of the supply voltage has dropped below a first voltage level for a first amount of time; in response to determining that the voltage level has dropped below the first voltage level for the first amount of time, issuing a command to place an operation on the memory circuit into a suspended state; subsequently continuing to monitor by the memory circuit of the voltage level of the voltage supply; while the operation on the memory circuit is in a suspended state, determining whether the voltage level of the supply voltage risen above a second voltage level for a second amount of time; in response to determining that the voltage level has risen above the second voltage level for the second amount of time, issuing a command to resume the operation placed in a suspended state; and completing the resumed operation.
