Abstract :
A full wafer mask programmable ROM incorporating 4Mb modules and module-selecting circuits on a 3" wafer, developed for a Chinese ideograph character generator, will be described. Memory cell has multigate MOS structure similar to CCD. Defect tolerant technology with duplicated block configuration has been used for yield enhancement.
