Claim 1:
2. The page buffer circuit of claim 1, wherein
each of the plurality of page buffers is configured to perform a first precharge operation that precharges the sensing node in response to a load signal, a first read operation that stores the inverted data that are inverted from the data of the storage node to the sensing node in response to a read signal, and a first write operation that stores the inverted data of the sensing node to the storage node in response to a write signal,
the first refresh operation includes the first precharge operation, the first read operation, and the first write operation,
