摘要： A semiconductor integrated circuit device includes dynamic latches, switch circuit, capacitor, first static latch, and first transfer gate. In refreshing data of the dynamic latches, data stored in the first static latch is moved to the second node through the first transfer gate and saved. The data of the dynamic latch is bootstrapped. The bootstrapped data is transferred to the first node to distribute charges, thereby setting the potential of the first node. The set potential is written back to the dynamic latch to refresh it. The saved data of the second node is moved to the first node through the first transfer gate and written back to the first static latch.

摘要： A write controller performs verification for checking whether each memory cell is on a predetermined verification level. For a memory cell to be written to a voltage level higher than the predetermined verification level, the write controller stores, in first and second latch circuits, the number of times of write to be performed by a write voltage after the verification. Whenever write is performed by the write voltage, the write controller updates the number of times of write stored in the first and second latch circuits. After write is performed the number of times of write by the write voltage, the write controller performs write by an intermediate voltage lower than the write voltage.

摘要： A semiconductor memory device includes a memory cell group, a selection transistor, a page buffer, and a row decoder. The memory cell group includes memory cell transistors connected in series. The selection transistor is connected to the memory cell transistor. The page buffer is adopted to apply first and second voltages to the bit lines connected to the memory cell transistors in which the “0” data and “1” data is to be programmed respectively, when the selection transistor is turned on, in a write operation. The page buffer is adopted to put the bit line into electrically floating after the first voltage and the second voltage are applied. The row decoder is adopted to apply a third voltage to a semiconductor layer on which the memory cell transistors are formed, and apply a program voltage to the selected word line when the bit line is in the electrically floating.
