Title: DETERMINATION OF DEMARCATION VOLTAGE FOR MANAGING DRIFT IN NON-VOLATILE MEMORY DEVICES
Abstract:
A predetermined pattern of bits is written to a non-volatile memory device prior to powering down the non-volatile memory device. A plurality of voltages are applied to the non-volatile memory device to determine which voltage of the plurality of voltages allows the predetermined pattern of bits to be read with a least amount of error. The determined voltage is set to be a demarcation voltage for reading from the non-volatile memory device.
