CIRCUIT FOR ACCURATE MEMORY READ OPERATIONS

摘要

A memory circuit arrangement for sensing current in a target cell (305) during a read operation is disclosed. According to one exemplary embodiment, the memory circuit arrangement comprises the target cell (305) and a first neighboring cell (355) adjacent to the target cell (305). The first target cell (305) has a first bit line (316) connected to ground (365); the target cell (305) also has a second bit line (321) connected to a sensing circuit (360). The first neighboring cell (355) shares the second bit line (321) with the target cell (305); the first neighboring cell (355) also has a third bit line (341) connected to the sensing circuit (360) during the read operation. The memory circuit arrangement results in increased error margins in a fast and accurate manner during the read operation of the target cell (305).
