    摘要: A semiconductor memory device includes a memory cell array, an address part for supplying address signals to the memory cell array, a read/write part for reading data from the memory cell array and writing data into the memory cell array, and an internal clock signal generating circuit for generating an internal clock signal from an external clock signal. The internal clock signal has a cycle with an active-level portion of constant duration independent of a frequency of the external clock signal and is output, as a timing signal, to predetermined structural parts of the address part and/or the read/write part.

    摘要: A semiconductor memory device includes a memory cell array in which a number of sense amplifiers are provided, a plurality of segmented drive lines each connected to a group of sense amplifiers for driving the same, each of the segmented drive lines being formed of first and second drive line segments forming a pair, and a number of trunks for supplying electric power to the segmented drive lines. Each of the trunks includes a first conductor strip extending from a first side of the memory cell array toward a second side for connection to a plurality of the first drive line segments upon crossing the same, and a second conductor strip extending from the second side of the memory cell array toward the first side for connection to a plurality of the second drive line segments upon crossing the same. The first and second conductor strips have distal end parts having a reduced width and a mutually complementary shape, such that the first and second conductor strips are disposed to form a straight strip having a substantially constant width throughout the memory cell array.
