Voltage detection circuit control device, memory control device with the same, and memory card with the same

摘要

A voltage detection circuit control device includes a first voltage detection circuit which detects a first voltage, a second voltage detection circuit which detects a second voltage higher than the first voltage, and an operation signal generating circuit which is connected to the first and second voltage detection circuits and produces a signal for controlling an operation of the first voltage detection circuit on the basis of a voltage detection signal from the second voltage detection circuit.
