Abstract
A memory system includes a first controller, a nonvolatile memory connected to the first controller, and a power supply circuit that applies a voltage to the first controller and the nonvolatile memory. The first controller writes first data to a first address in the nonvolatile memory and instructs the power supply circuit to apply the destruction voltage to the nonvolatile memory. The first controller determines whether the first data can be correctly read from the first address in the nonvolatile memory and checks destruction of the nonvolatile memory based on the determination.
