Abstract

A sensing circuit with adaptive local reference generation of a resistive memory is configured to adaptively sense a first bit line current of a first bit line and a second bit line current of a second bit line via one sense amplifier. The sense amplifier has a first output node and a second output node. The adaptive local reference generator is electrically connected to the sense amplifier and generating a reference current equal to a sum of the second bit line current and a local reference current. A first bit line current flows through the first output node during a first bit line time interval. A second bit line current flows through the first output node during a second bit line time interval. The first bit line time interval is different from the second bit line time interval.
