MEMORY SYSTEM AND METHOD OF CONTROLLING MEMORY SYSTEM

According to an embodiment, a memory device includes a nonvolatile first memory, a nonvolatile second memory, a first controller, and a second controller. The first controller is configured to write, to the first memory, data received over a short-range radio communication by using power generated in the short-range radio communication. The second controller is configured to execute, at a startup of the memory device, a transfer process of reading a file written in the first memory and storing the read file to the second memory.
