Abstract
PURPOSE:To shorten a time necessary for precharging action without generating a voltage level difference by shortcircuiting the complementary data lines of a static type RAM for a prescribed period of time after activating the RAM to halfprecharge them. CONSTITUTION:The static type RAM SRAM is basically constituted of two sets of memory arrays M-ARY1 and M-ARY2 which are constituted of word-line couples disposed in a horizontal direction and complementary-data-line couples disposed in a vertical direction and memory cells disposed at the crossing points of said data lines and word lines in grid-shaped formation. And one one of respective adjacent two-set complementary data line, a means to supply a power source voltage for the semiconductor memory, a means to supply the other couple with a ground voltage for the semiconductor memory, and a means to equalize said complementary-data-line set are provided. Accordingly, level difference is hardly occurred between these complementary-data-line sets, hence the inverting of the information stored in a memory cell can be prevented, and the semiconductor memory can be speeded up without lowering read margin.
