An information processing apparatus includes a memory, a control unit to accept an access to the memory, a power supply circuit to supply a voltage to the memory and the control unit, a detection circuit to detect a drop in the voltage, a discharge circuit, and a delay circuit. The discharge circuit discharges a charge on a voltage supply line extending between the power supply circuit and the memory. The delay circuit delays receipt of a control signal by the discharge circuit for a predetermined period after the discharge circuit receives a charge discharge instruction from the control unit. The control signal is to control discharging the supply line charge. The discharge circuit discharges supply line charges per a control signal based on detection of a drop in the voltage by the detection circuit and based on the delay of the control signal delayed by the delay circuit.
