Abstract
A semiconductor memory apparatus includes a plurality of bit lines, a plurality of page buffers, and a page buffer control circuit. The plurality of page buffers are each coupled with the plurality of bit lines and operate in response to a plurality of page buffer control signals. The page buffer control circuit generates the plurality of page buffer control signals to perform program and verification operations comprising a plurality of loops. The page buffer control circuit uses the plurality of page buffer control signals to simultaneously precharge bit lines coupled with page buffers, among the plurality of page buffers, corresponding to a plurality of verification levels corresponding to each of the plurality of loops.
