Claim:
1. A method comprising: determining, by a control unit of a memory device comprising a first memory cell, a voltage level of the first memory cell in an erased state; receiving, at the control unit from a host device, a first request to store a first data to the memory device comprising the first memory cell; encoding, by the control unit, the first data to generate an encoded first data, wherein a logical value of the encoded first data corresponding to a least significant bit of the first memory cell is a predetermined logical value regardless of a content of the first data when the voltage level of the first memory cell is within a predetermined voltage range; and storing, by the control unit, the logical value of the encoded first data to the least significant bit of the first memory cell, wherein encoding the first data further comprises encoding the first data using a decodable function that provides the predetermined logical value for the least significant bit of the first memory cell when the voltage level of the first memory cell is greater than a predetermined threshold.
