| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a memory system allowing reduction in the time for reading a data page.SOLUTION: A storage device comprises: a nonvolatile memory 100 having a plurality of data pages 102 that are composed of a predetermined number of bits; and a controller 110 that requests the output of a bit status. The nonvolatile memory 100 has a logic circuit 103 that verifies the logic values of the bits when receiving a request to output the bit status; and outputs a logic value, which indicates that writing is enabled or disabled for all the bits, to the controller. |
