Abstract
According to one embodiment, a memory controller allows access to a first non-volatile memory from a host device when a wireless communication unit is communicable or communicating with any one of wireless communication devices, and denies access to the first non-volatile memory from the host device when the wireless communication unit is not communicable or communicating with any one of the wireless communication devices. The memory controller does not allow the host device to access information in the first non-volatile memory after the access field specification information is updated.
Claims14
A memory system capable of wireless communication comprising:
- a wireless communication unit;
- a first non-volatile memory;
- a second non-volatile memory that stores access field specification information including wireless communication device identification information that identifies one or more wireless communication devices, the wireless communication device identification information being access point identification information that identifies an access point connected to a network and serving as a wireless base station;
- and
- a memory controller that controls data access between a host device and the first non-volatile memory and manages a wireless connection state of the wireless communication unit, wherein
- the memory controller:
- allows access to the first non-volatile memory from the host device when the wireless communication unit is communicable or communicating with any one of the wireless communication devices that is registered in the access field specification information, and denies access to the first non-volatile memory from the host device when the wireless communication unit is not communicable or communicating with any one of the wireless communication devices that is registered in the access field specification information, wherein
- a state that the wireless communication unit is communicable or communicating with any one of the wireless communication devices is a state in which the memory system has entered a wireless communication area of any one of the wireless communication devices or a state in which the memory system is performing wireless communication with any one of the wireless communication devices.

A method of controlling a memory system including a wireless communication unit, a first non-volatile memory, and a second non-volatile memory, the method comprising:
- receiving an instruction to register one or more wireless communication terminals in access field specification information in the second non-volatile memory, the access field specification information including identification information of the wireless communication terminals, the access field specification information identifying an access point connected to a network and serving as a wireless base station;
- receiving an instruction to access the memory system from a host device;
- and
- determining whether to allow or deny the access instruction by referring to a connection state between the wireless communication unit and any one of the wireless communication terminals, wherein
- in the determining whether to allow or deny the access instruction, the access instruction is allowed when the wireless communication unit is communicable or communicating with any one of the wireless communication terminals that is registered in the access field specification information, and the access instruction is denied when the wireless communication unit is not communicable or communicating with any one of the wireless communication terminals that is registered in the access field specification information, wherein
- a state that the wireless communication unit is communicable or communicating with any one of the wireless communication terminals is a state in which the memory system has entered a wireless communication area of the access point or a state in which the memory system is performing wireless communication with the access point.
