Abstract
A storage device according to an embodiment includes first and second non-volatile semiconductor memories. In addition, the storage device includes first controller that controls the first non-volatile memory to cause the first non-volatile memory to perform processes. In addition, the storage device includes second controller that controls the second non-volatile memory to cause the second non-volatile memory to perform processes. The storage device further includes a signal line which is connected to the first controller and the second controller and through which a token is transmitted between the first controller and the second controller. The first controller is capable of controlling the first non-volatile memory while holding the token and the second controller is capable of controlling the second non-volatile memory while holding the token.
