    摘要: A semiconductor memory device has a hierarchical bit line structure. The semiconductor memory device may include first and second memory cell clusters, which share the same bit line pair and are divided operationally; third and fourth memory cell clusters, which are connected respectively corresponding to word lines coupled with the first and second memory cell clusters, and which share a bit line pair different from the bit line pair and are divided operationally; and a column pass gate for switching one of bit line pairs connected with the first to fourth memory cell clusters, to a common sense amplifier, in response to a column selection signal. Whereby an operating speed decrease caused by load of peripheral circuits connected to the bit line is improved, and the number of column pass gates is reduced substantially with a reduction of chip size.

    摘要: A data line layout structure comprises a plurality of first data lines, second data lines, a third data line, a first data line driver, and a second data line driver. The plurality of first data lines are connected to sub mats in a memory mat so that a predetermined number of first data lines are connected to each sub mat. The second data lines are disposed in a smaller quantity than the number of the first data lines so as to form a hierarchy with respect to the first data lines. The third data line is disposed to form a hierarchy with respect to the second data lines, and transfers data provided through the second data lines to a data latch. The first data line driver is connected between the first data lines and the second data lines, and performs a logical ORing operation for output of the first data lines so as to drive a corresponding second data line. The second data line driver is connected between the second data lines and the third data line, and performs a logical ORing operation for output of the second data lines so as to drive the third data line.
