Abstract:
A data storage device is disclosed comprising a non-volatile memory. A supply voltage for powering the non-volatile memory is sampled to generate supply voltage samples. A power loss threshold is adjusted based on the supply voltage samples, and a power loss event is detected based on the power loss threshold and the supply voltage, wherein an emergency operation is executed when the power loss event is detected.
