Data conversion with data path circuits for use in double sense amp architecture with fractional bit assignment in non-volatile memory structures

A method for programming a non-volatile memory structure, comprises initiating a two-dimensional fractional number of bits-per-cell programming scheme of a plurality of memory cells, wherein the memory structure comprises: (1) a first memory array comprising a first population of memory cells and the associated peripheral circuitry disposed below the first population of cells, (2) a second memory array positioned above the first memory array and comprising a second population of memory cells and associated peripheral circuitry disposed above the second population of cells, and (3) a data bus tap electrically coupling the first and second memory arrays. Further, the method comprises: (1) storing input data in data latches associated with the first array and with the second array. Additionally, the method comprises converting the stored data using data conversion logic implemented by a data path circuit of the first and second arrays and rewriting the converted data to the latches.
