Abstract
A selection circuit for sensing current in a target cell during a memory read operation is disclosed. According to one embodiment, the selection circuit comprises a sensing circuit selector connected to a sensing circuit and a ground selector connected to ground. The ground selector connects a first bit line of the target cell to ground, and the sensing circuit selector connects a second bit line of the target cell to the sensing circuit. The sensing circuit selector also connects a third bit line of a first neighboring cell to the sensing circuit. The first neighboring cell shares the second bit line with the target cell.
