Abstract:
A nonvolatile memory card comprising:a control circuit; a nonvolatile memory including a plurality of memory cells for accommodating data, each of said memory cells having a threshold voltage corresponding to data held therein; an error correcting circuit; and an output circuit, wherein data read from memory cells selected from among said plurality of memory cells are supplied to said error correcting circuit and said output circuit, wherein said error correcting circuit generates syndromes to indicate whether the data includes any error and supplies said output circuit with an error status flag to indicate whether any error is included in the data read from the selected memory cells, wherein said output circuit outputs said data from said selected memory cells as well as said error status flag, and wherein said error correcting circuit detects a location of the error in said data read by said output circuit from said selected memory cells, and corrects said error.
