Abstract
A reset control circuit for an EAROM includes a zener diode coupled across the input of a voltage regulator which supplies operating voltage for the EAROM. The breakdown voltage of the zener diode is greater than the output voltage of the regulator. During turn-on, the reset voltage, which is taken from the zener diode, is held below the low point of its active region until the operating voltage has been established. During turn-off, the operating voltage is maintained until the reset voltage has become inactive, i.e. has dropped below its reset low voltage. The sequencing of operating voltage and reset voltage protects the data in the EAROM.
