    Abstract: A semiconductor memory device comprises a driver including a first resistor, and a control signal generator including a second resistor. A storage unit is employed to store adjustment data for setting a resistance of said second resistor at a designed resistance, which is specified based on the state of the control signal actually obtained when the resistance of the second resistor is set to a certain designed value. The storage unit is referred to for stored data to switch the second resistor to control the state of the control signal. In addition, the first resistor is switched to a resistance corresponding to the resistance of the second resistor.

    Abstract: A semiconductor memory device includes a memory cell array, data buffer, and column switch. The data buffer senses the potential of a bit line to determine data in a selected memory cell and hold readout data in a read. The data buffer detects both whether the whole data buffer holds “0” data and whether the whole data buffer holds “1” data. The column switch selects part of the data buffer and connects the part to a bus.

    Abstract: The memory device according to an embodiment of the invention prepares a reference field (reference value range) corresponding to each logical value and if the threshold value of the cell is within that field, the cell is determined to be defective and the data of the defective cell is stored in a redundant cell. Therefore, if the threshold value drops because the cell charge leaks over time, the data which is stored can be rescued. As a background operation of a normal operating, memory device performs the memory cell check and memory cell substitution in accordance with the internal addresses generated independently than external addresses. Therefore, a defective cell can be rescued without causing delay in the normal operations of memory device.
