Abstract
A method of manufacture of a low-capacitance programmed cell structure for read-only memory circuits comprises a field-effect transistor having conventional source and drain regions separated by a channel region overlaid by the gate of the transistor. This ROM memory cell is programmed by a channel implant extending only from the source region for a selected distance into the channel region.
