Abstract: A memory system includes a first non-volatile memory and a control circuit. The first non-volatile memory operates in one of a plurality of operation modes including at least a first operation mode and a second operation mode. The control circuit switches the operation mode of the first non-volatile memory based on an operation mode switching information received from an external device.

Abstract: A storage device includes an antenna, a first nonvolatile memory that is operable using power generated at the antenna by an electromagnetic induction caused by an external device, and stores lock state information, a first controller configured to change the lock state information in response to a command that is wirelessly transmitted from the external device through the antenna, a second nonvolatile memory, and a second controller configured to allow access to a memory region of the second nonvolatile memory depending on the lock state information stored in the first nonvolatile memory.

Abstract: A storage apparatus includes a first memory, which is nonvolatile, a first controller that controls the first memory, a wireless antenna, a second memory, which is operable based on power supplied from the wireless antenna, and a second controller that is operable based on the power supplied from the wireless antenna, and performs communication using the wireless antenna. When performing communication with an external apparatus using the wireless antenna, the second controller performs authentication of the external apparatus, and stores in the second memory an authentication result indicating whether the authentication succeeded or failed. If the authentication result indicates that the authentication succeeded, the second controller permits reading by the external apparatus of first data from the second memory by communication using the wireless antenna or writing by the external apparatus of second data to the second memory by communication using the wireless antenna.
