  • Publication number: 20080212385
    Abstract: According to one embodiment a semiconductor device is provided. The device includes a first compensator to generate a first compensated signal and a first limiter to control operation of the first compensator. Furthermore, a second compensator to generate a second compensated signal and a second limiter to control operation of the second compensator is provided. An output device is adapted to receive the first compensated signal and the second compensated signal to drive an output.

    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.

  • Publication number: 20080170455
    Abstract: A sensing circuit with current offset functionality. In one embodiment, the sensing circuit includes a memory circuit having a first offset circuit operative to offset a first current. The sensing circuit also includes a reference circuit coupled to the memory circuit, where the reference circuit includes a second offset circuit operative to offset a second current. The sensing circuit also includes a compare circuit coupled to the memory circuit and the reference circuit, where the compare circuit determines the state of a memory cell based on first current and the second current. According to the system disclosed herein, the first and second offset circuits optimize the performance of the sensing circuit and prevent errors when determining the state of the memory cell.
