  • Publication number: 20220208270
    Abstract: A method for programming three page user data in a memory array of a non-volatile memory system, comprising converting each three-bit value data pattern of the user data into a representative pair of two-bit data values, simultaneously programming two single-state memory cells with a first of the pair of representative two-bit data values, wherein the two single-state memory cells are located along a first common word line of two memory cell strings, and simultaneously programming two single-state memory cells with a second of the pair of representative two-bit data values, wherein the two single-state memory cells are located along a second common word line of the two memory cell strings.

  • Patent number: 10910044
    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.
