Abstract
A data sensing apparatus adapted for sensing read-out data of a memory apparatus includes a sensing reference voltage generator, a sensing reference current generator, and a sense amplifier. The sensing reference voltage generator receives a reference voltage, generates a reference current according to the reference voltage and a control signal, and generates a sensing reference voltage according to the reference current. The sensing reference current generator receives the sensing reference voltage, and generates a sensing reference current according to the sensing reference voltage and the control signal. The sense amplifier receives the sensing reference current and a read-out current from the selected memory cell, and senses a current difference between the sensing reference current and the read-out current to generate the read-out data.
