ABSTRACT:
A battery backup circuit for a CMOS RAM is isolated from the negative, or ground, power supply rail of the memory so that the memory is held at a potential which is sufficiently different from that of the normal write-enable signal (usually zero volts) to prevent spurious signals from affecting the memory.
