Abstract:
Various embodiments of the present invention provide for extended life operation of multi-bit memory cells. As an example, some embodiments of the present invention provide electronic systems that include a plurality of multi-bit memory cells, an encoding circuit and a decoding circuit. Each of the plurality of multi-bit memory cells is operable to hold at least two bits. The encoding circuit is operable to receive a data input including at least two data bits, and to encode the two data bits as an encoded output to the plurality of multi-bit memory cells. The encoded output may be selected to be either a single two bit output representing the two bits, or a series of two two bit outputs representing the two bits. The decoding circuit is operable to reverse the encoding applied by the encoding circuit.
