Abstract
A method for controlling a sense amplifier chronologically includes an idle phase, an offset cancellation phase, a charge sharing phase, and a sensing and amplification phase. In the charge sharing phase, the method includes controlling the first node to connect to the complementary bit line for a first predetermined duration and the second node to connect to the bit line for the first predetermined duration, and then disconnecting the connection between the bit line and the second node and the connection between the first node and the complementary bit line. In the sensing and amplification phase, the method include controlling the first node to connect to the complementary bit line and the second node to connect to the bit line, so as to transmit an amplified voltage to the bit line and the complementary bit line.
