  • Patent number: 11430525
    Abstract: According to one embodiment, a memory device, includes a first memory cell, and a second memory cell adjacent to the first memory cell; and a sequencer configured to, when data is read from the first memory cell: perform a first read operation on the second memory cell; perform a second read operation on the first memory cell; perform a third read operation on the first memory cell by applying a voltage different from that applied in the second read operation to a gate of the second memory cell; and generate first data stored in the first memory cell and second data for correcting the first data, based on results of the first to third read operations.
    Type: Grant

  • Publication number: 20110228605
    Abstract: A nonvolatile memory includes a memory cell array comprising an object block which includes a first data bit region capable of storing input data and a first flag bit region capable of storing first flag information, a redundant block which includes a second data bit region capable of storing input data and a second flag bit region capable of storing second flag information, and a special block including a special bit region capable of storing an object block address of the object block. The nonvolatile memory includes an object block retention part which retains the object block address. The nonvolatile memory includes an object block flag storage part which stores the first flag information therein. The nonvolatile memory includes a redundant block flag storage part which stores the second flag information. The nonvolatile memory includes a coincidence detection circuit which detects whether a block address which is input coincides with the object block address retained in the object block retention part.
