Abstract
The present technology relates to a page buffer and a semiconductor memory device including the same. The page buffer includes a bit line selector configured to connect a bit line of a memory cell array to a sensing node, a precharger configured to precharge a potential of the sensing node to a first level, and a latch component configured to sense data by detecting a time at which the potential of the sensing node is decreased from the first level to a second level.
