SELECTION CIRCUIT FOR ACCURATE MEMORY READ OPERATIONS

摘要

A selection circuit for sensing current in a target cell (305) during a memory read operation is disclosed. According to one embodiment, the selection circuit comprises a sensing circuit selector (364) connected to a sensing circuit (360) and a ground selector (362) connected to ground (365). The ground selector (362) connects a first bit line (316) of the target cell to ground, and the sensing circuit selector (364) connects a second bit line (321) of the target cell (305) to the sensing circuit (360). The sensing circuit selector (364) also connects a third bit line (341) of a first neighboring cell (355) to the sensing circuit (360). The first neighboring cell (355) shares the second bit line (321) with the target cell (305).
