Abstract
A memory system includes a nonvolatile memory and a memory controller. The memory controller is configured to: execute a first tracking process to determine a value of a first voltage in a patrol process that is carried out independently of a request from a host, execute a first data read process to read first data from the nonvolatile memory in response to receiving a read request from the host, cause the nonvolatile memory to execute a second tracking process using the first voltage when error correction of the first data fails, receive a value of a second voltage from the nonvolatile memory as a result of the second tracking process, and execute a second data read process using the second voltage to read second data from the nonvolatile memory.
