Protection circuit for memory programming system |
摘要 |
A protection circuit inhibits the generation of a write-erase signal to an E2PROM when the logic supply voltage falls below a predetermined threshold level. A differential-input amplifier compares the logic supply voltage with a fixed potential and when the logic voltage drops below the threshold, a transistor coupled to the write-erase signal generator switches to its conductive state inhibiting further occurrences of the signal.
