  • Patent number: 8107308
    Abstract: A semiconductor memory device is provided. A memory cell array has a plurality of memory cells connected between a plurality of word lines and a plurality of bit-line pairs. A sense amplifier unit has a plurality of sense amplifiers connected with the bit-line pairs respectively and amplifies data of the bit-line pairs to a sensing voltage level. A command decoder decodes a command applied from the outside and outputs the decoded command. A plurality of input/output (I/O) gates electrically connects the bit-line pairs with corresponding I/O line pairs in response to a voltage level applied through a plurality of corresponding column selection lines. A column decoder decodes a column address and drives at least one of the column selection lines to a plurality of different voltages levels.
