ABSTRACT:
A sensing circuit. In one embodiment, the sensing circuit includes a memory circuit including a first bitline that sinks a first leakage current, a compensation device coupled to the memory circuit, and a compensation circuit coupled to the compensation device. The compensation circuit includes a second bitline that sinks a second leakage current that matches the first leakage current. The compensation device is operative to compensate the first leakage current through a current based on the second leakage current. According to the system and method disclosed herein, the compensation device and compensation circuit prevents errors when determining the state of the memory cell.
