ABSTRACT:
A semiconductor storage device includes: a memory cell array including a plurality of memory cells which are connected to a plurality of pairs of complementary bit lines; an internal voltage decreasing section for generating a predetermined voltage lower than a power supply voltage; and an equalizing section for performing an equalizing operation to charge the pairs of complementary bit lines to a predetermined equal potential, wherein the internal voltage decreasing section is formed by first and second internal voltage decreasing sections, the equalizing section is formed by a first equalizing section, which is provided at one side of the memory cell array, and a second equalizing section, which is provided at the other side of the memory cell array, the first and second internal voltage decreasing sections supply an electric power to the first and second equalizing sections, respectively.
