摘要：
A semiconductor memory device includes a first nonvolatile memory which has a first external interface and is capable of recording 1-bit data in one memory cell, a second nonvolatile memory which has a test terminal interface and is capable of recording a plurality of data in one memory cell, and a control unit which has a second external interface and is configured to control a physical state of an inside of the second nonvolatile memory.
