    摘要: In conventional memory arrays in which a bit line is shared by memory cells, a cell current flows over into neighbor cell(s) in a program verify process, and therefore, the threshold of a memory cell to be programmed is erroneously determined to be lower. Therefore, in a program verify process, a control circuit 3 writes a fail value to a neighbor cell buffer 5 when all neighbor cell(s) having an offset of n or less from a memory cell to be programmed are in the erased state, and when otherwise, writes a pass value to the neighbor cell buffer 5. The control circuit 3 verifies input write data and also verifies data stored in the neighbor cell buffer(s). In the latter verify process, a verify voltage higher than an ordinary one is used to compensate for the leakage of cell current.

    摘要: To provide a nonvolatile memory microcomputer with which a step of testing a microcomputer unit using a logic tester can be omitted, thereby reducing the testing cost. A memory tester supplies test data and expectation data to the nonvolatile memory microcomputer, and the nonvolatile memory microcomputer stores them in a nonvolatile memory. Subsequently, upon receiving an address signal, the nonvolatile memory outputs a test signal and an expectation signal based on test data and expectation data corresponding to the address signal. The test signal is supplied to a circuit block in the microcomputer unit, to drive the circuit block. The circuit block returns a test result signal, which is output to the memory tester together with the expectation signal. The memory tester compares the test result signal and the expectation signal, to judge whether the microcomputer unit operates correctly.

    摘要: An n-bit status signal indicating an execution state of a write command is outputted from a status register. At the time of data writing, an output switching circuit outputs (n×m)-bit data in which a status signal pattern repeats m times. At the time of data reading, the output switching circuit outputs data stored in a memory cell array.

    摘要: The non-volatile semiconductor storage device 101 includes the specific command Enable/Disable signal lines 120 connected to the command decoder 108. The specific command Enable/Disable signals are externally inputted to the command decoder 108 through the signal lines 120. Thereby, when the device 101 is initialized, the command decoder 108 enables the specific command and the device 101 can shift to a mode corresponding to the specific command. On the other hand, the command decoder 108 can disable the specific command, for example, when a user uses the device 101, thereby preventing the specific command from being executed even when the specific command is erroneously issued.
