Abstract
An information processing apparatus which is capable of preventing a malfunction of a storage using flash memory caused by a decrease in the number of free blocks. The information processing apparatus controls a storage that includes a nonvolatile memory and a memory controller that controls the nonvolatile memory. The number of free blocks in the nonvolatile memory is detected, and in accordance with the detected number of free blocks, the memory controller is instructed to switch to one of the following writing modes: a first writing mode in which the memory controller writes data to the nonvolatile memory without performing garbage collection, and a second writing mode in which the memory control unit writes data to the nonvolatile memory and then performs garbage collection.
