ABSTRACT:
A microprocessor includes an internal data memory, made up of a plurality of memory cells, each of which includes first and second inverter circuits. In selected memory cells, the logic state of the cell is predetermined upon initiation of the power supply by arranging the inverters of each cell such that they have different transistor ratios. The difference in ratio may be effected by altering the channel width or length of one of the constituent transistors of the respective inverter circuit.
