Abstract
A sensing amplification circuit includes a sensing amplifier and a trigger control circuit. The sensing amplifier receives a data voltage and a reference voltage, and outputs a first data signal and a second data signal by comparing the data voltage and the reference voltage. The trigger control circuit includes a logic circuit and a set-reset latch. The logic circuit receives the first data signal and the second data signal, and changes a first control signal from a first voltage level to a second voltage level when one of the first data signal and the second data signal changes its state. The first set-reset latch receives the first control signal and a second control signal, and generates a trigger signal to enable the sensing amplifier when the second control signal changes state and disable the sensing amplifier when the first control signal changes state.
