Abstract
According to one embodiment, an information processing system includes a host and memory systems. A first memory system stores first data in a nonvolatile memory. A second memory system stores second data in a nonvolatile memory. The host transmits first update data to the first memory system and transmits second update data to the second memory system. The first memory system generates first XOR data by performing an XOR operation on at least the first data and the first update data, and transmits the first XOR data to the second memory system. The second memory system generates second XOR data by performing an XOR operation on the second data, the second update data, and the first XOR data, and transmits the second XOR data to a third memory system.
