Abstract
A circuit for prevention of unintentional writing to a memory prevents unintentional writing to a nonvolatile memory, after a recovery from a transitory power failure. The circuit includes a low-voltage detection circuit for detecting a power supply voltage drop depending on the state of a control signal for the detection circuit. A writing operation to the memory is prohibited depending on the control signal as well as upon an output signal of the low-voltage detection circuit.
