External exclusive OR type circuit for inverting cell MOS RAM

摘要: External Exclusive OR type circuitry is coupled to an MOS RAM utilizing inverting storage cells and a data control register associated therewith. Bit sense lines of the are first terminal by coupling circuit line second circuit. The external has inputs connected terminals RAM. In one embodiment, metal masking option utilized during fabrication chip connects bit internal output instead circuits, in which case not utilized. Use provides shorter access time for
