摘要： According to one embodiment, a device includes a cell array including an ordinary area, a hidden area, and an identification information record area in which identification information which defines a condition for accessing the hidden area is recorded. An authentication circuit performs authentication. A sensing circuit recognizes information recorded in the identification information storage area, determines the information recorded in the identification information record area when an access request selects the hidden area, validates an access to the hidden area when determined that the identification information is recorded, and invalidates an access to the hidden area when determined that the identification information is not recorded.
