摘要：A page buffer circuit with reduced size and methods for reading and programming data is provided. In the reading operation, the page buffer circuit reads out a data bit by alternatively using a higher bit register or a lower bit register regardless of whether the data bit read from the multi-level cell is a higher bit or a lower bit, thereby reducing the circuit area and improves the performance of operation.
