MEMORY SYSTEM CAPABLE OF WIRELESS COMMUNICATION AND METHOD OF CONTROLLING MEMORY SYSTEM

摘要

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.

主权项

1. 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; 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, 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; anddoes not allow the host device to access information in the first non-volatile memory after the access field specification information is updated.
