ABSTRACT:
An I.sup.2 L programmable read only memory (PROM) row driver circuit sinks current from a row of memory elements when selectively activated. The circuit operates in the read mode at very low power levels and down to 1.0 volt. The circuit has two current sinking capabilities, a low current capability for the read mode and a high current capability for the program mode. Switching between modes is accomplished merely by changing the voltage on a power supply terminal; 1-3 volts for the read mode and 9-12 volts for program.
