Abstract
A memory device includes a memory cell array and a sensing amplifier circuit. The memory cell array outputs a cell current. The sensing amplifier circuit is coupled to the memory cell array to receive the cell current. The sensing amplifier circuit includes an operational amplifier. The operational amplifier includes a first input terminal, a second input terminal, and an output terminal. The sensing amplifier circuit pulls up a voltage at the first input terminal to a first voltage by a first capacitor according to the cell current in a developing mode, and pulls up the voltage at the first input terminal to a second voltage higher than the first voltage in a boost mode after the developing mode by a second capacitor and the first capacitor. The output terminal outputs data according to the voltage and a reference voltage at the second input terminal.
