Abstract

An information processing apparatus that is capable of securing electric power needed to complete data writing to a nonvolatile memory even if supplied voltage drops. The information processing apparatus includes a nonvolatile memory, a volatile memory that caches write data to the nonvolatile memory. A first power supply unit generates electric power supplied to the nonvolatile memory and the volatile memory by a switching operation. A power source controller lowers a switching frequency of the first power supply unit and controls the first power supply unit to supply the electric power to the nonvolatile memory and the volatile memory in a case where voltage supplied to the information processing apparatus drops.
