Abstract
A page buffer circuit includes a plurality of page buffers connected to a plurality of bitlines. Each of the plurality of page buffers includes a bitline selection transistor configured to connect a corresponding bitline of the plurality of bitlines to a sensing node, a precharge circuit configured to precharge the sensing node, and a dynamic latch circuit configured to store data in a storage node. Each of the plurality of page buffers is configured to refresh the data stored in the storage node through charge sharing between the storage node and the sensing node.
