Abstract
Technology is described for generating a valid token control signal from control signals from a row driver. In one example, a matrix type integrated circuit includes a row driver module and a 2D array of cell elements. The row driver module includes a voting logic module and at least two row drivers configured to generate control signals on at least two communal lines for cell elements of a row of the 2D array. Each row driver is configured to generate control signals on at least three control lines where at least two control lines are the communal lines and coupled to a corresponding communal line of another row driver. The voting logic module is coupled to the at least three control lines of one of the row drivers and configured to generate an output based on the control signals on the at least three control lines.
