摘要: A semiconductor memory device includes a memory cell array, a page buffer, a data line pair, a differential amplifier and a precharger. The memory cell array includes a plurality of pages in which a plurality of memory cells are arranged. The page buffer is formed adjacent to the memory cell array, and includes a plurality of sense amplifiers configured to temporarily hold page data read from the memory cells in the page. The data line pair is arranged in the page buffer and is connected to the sense amplifiers. The differential amplifier is configured to amplify a potential difference between lines of the data line pair. The precharger is configured to precharge the data line pair to a predetermined potential. At least one of the differential amplifier and the precharger is formed in the page buffer, and the at least one circuit is electrically connected to the data line pair.
