A multiple level logic memory device is achieved. The device comprises, first, a plurality of memory cells capable of storing an analog voltage. Second, there is included a means of converting an external data word value comprising one value of a set of at least three possible values into a writing analog voltage corresponding to the external data word value. Third, a means of decoding an external address value in response to a write command such that the writing analog voltage is electrically coupled to the memory cell is included. Fourth, there is included a means of converting the memory cell analog voltage into an external data word value comprising one value of the set of at least three possible values corresponding to the memory cell analog voltage. Finally, a means of encoding the external address value in response to a read command such that the memory cell analog voltage is electrically coupled to the means of converting the memory cell analog voltage is used.
