  • Virtual ground read only memory
    Patent number: 4638459
    Abstract: A dynamic read only memory (ROM) which comprises a memory select precharge section, a memory select section, a memory section, a memory precharge section and a plurality of grounding devices. The ground reference for the pulldown transistors is selectively activated at an appropriate time such that the memory sections are active only for a relatively brief portion of the memory cycle, thereby reducing dc power consumption and simplifying the driver circuit.
