COMPENSATED CURRENT OFFSET IN A SENSING CIRCUIT
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.
