Abstract

A sensing apparatus and data sensing method are provided. The sensing apparatus includes an initial circuit, a reference current generator and a sensing circuit. The initial circuit discharges a sensing end to a reference ground during a discharge period, and pre-charges the sensing end to a preset voltage level during a pre-charge period according to an output signal. The reference current generator draws a reference current from the sensing end. The sensing circuit senses a voltage level on the sensing end to generate the output signal. Wherein, the sensing end receives a cell current from a memory cell, and the pre-charge period is after the discharge period.
