    摘要: When any one of memory cells (MC.sub.1R, MC.sub.NR and MC.sub.1L, MC.sub.NL) connected with respective bit lines (3.sub.R, 4.sub.R and 3.sub.L, 4.sub.L) is addressed, the gate potential of a transfer transistor group (7.sub.R, 8.sub.R or 7.sub.L, 8.sub.L) connected with the bit lines on the non-selected side is clamped at bit line precharge voltage, whereby the said transfer transistor group (7.sub.R, 8.sub.R or 7.sub.L, 7.sub.L) is turned off. Thus, the bit lines on the non-selected side are cut off at a high speed from a sense amplifier.

    摘要: The single input gate electrode in a conventional CCD shift register is replaced by four spaced electrodes. The fourth electrode adjacent to the first transfer electrode has an area larger than that of the second electrode which always has a DC voltage applied thereto. Three driving pulses are applied in a predetermined sequence to the first, third and fourth electrodes while the two bit values of 2-bit information are written into the register and a charge is accumulated directly under the fourth input gate electrode at one of four levels as determined by the combination of the write bit values. Then the accumulated charge is stepwise transferred in the same manner as in conventional CCD shift registers.

    摘要: A semiconductor memory device comprises a plurality of memory cells arranged in a plurality of rows and columns, a plurality of row decoders for selecting one row of the plurality of rows, spare memory cells arranged in one row and a spare decoder for selecting the spare memory cells arranged in the one row. Each of the row decoders comprises a link element which can be melted by a laser beam. A plurality of decoder state determining logical circuits are provided corresponding to the plurality of row decoders. If and when a defective memory cell exists of the memory cells arranged in one row corresponding to each of the row decoders, the link element in the row decoder is melted in advance. When the row decoder having the link element melted in advance is selected by address signals, a corresponding decoder state determining logical circuit generates an SEE signal. The spare decoder is selected in place of the row decoder by the SEE signal.
