Abstract:
An apparatus includes a pair of memory cells configured to represent data using joint data states where one of the joint data states comprises an error-prone joint data state. The apparatus further includes an encoder configured to convert user data into joint data states according to a dual-cell gray-code encoding scheme in which the error-prone joint data state does not encode user data.
