Abstract
A device for generating sum-of-products data includes an array of variable resistance cells, variable resistance cells in the array each comprising a programmable threshold transistor and a resistor connected in parallel, the array including n columns of cells including strings of series-connected cells and m rows of cells. Control and bias circuitry are coupled to the array, including logic for programming the programmable threshold transistors in the array with thresholds corresponding to values of a weight factor Wmn for the corresponding cell. Input drivers are coupled to corresponding ones of the m rows of cells, the input drivers selectively applying inputs Xm to rows m. Column drivers are configured to apply currents In to corresponding ones of the n columns of cells. Voltage sensing circuits operatively coupled to the columns of cells.
