Abstract
According to one embodiment, an information processing apparatus includes a host and a memory system. The memory system includes a nonvolatile memory. The host includes a volatile memory, a first host control unit, and a second host control unit. The volatile memory includes a first area to be used by the host and a second area as a cache memory to temporarily store data of the nonvolatile memory. The first host control unit computes a first code, and stores the first data and the first code in the second area. The first code is redundant information of the first data. The second host control unit reads second data and a second code from the second area, performs error detection on the second data based on the second code, and transfers the second data. The second code is redundant information of the second data.
