Abstract
A digital-to-analog converter (DAC) and memory device includes an array of memory cells including resistive memory elements programmable between a high resistive and low resistive state. In implementations the array of memory cells is segmented into unary and binary coded sub-arrays. The device includes a binarizer configured to couple to the memory array to assign binary weights, or segmented unary and binary weights, to currents through a plurality of memory cells or voltages across a plurality of memory cells. The memory device further includes a summer to sum the weighted outputs of the binarizer. A current to voltage converter coupled with the summer generates an analog output voltage corresponding with digital data stored in a plurality of memory cells.
