ABSTRACT:
A read only memory integrated circuit includes a first group of transistors serving as the memory elements, and a second group of transistors in a memory peripheral circuit and integrated in the same substrate as the memory transistors. The base width of the first group of memory transistors is greater than that of the second group of transistors in the peripheral circuit.
