Semiconductor memory device

摘要

A semiconductor memory device includes a plurality of memory cells arranged in a matrix fashion, word lines each connected commonly to the memory cells arranged on the same row, plural pairs of data lines each pair connected commonly to the memory cells on the same column line, and a row decoder connected to the word lines. The semiconductor memory device further includes positive feedback amplifiers connected to the work lines, which respond to voltages on the word lines at a preset or higher level to pull up the potential on the word lines to a higher level.
