    Abstract: A sensing circuit includes a plurality of cell read current generators, a reference current generator and a plurality of sense amplifiers. Each of the cell read current generators generates a cell read current from each of a plurality of memory cells. The reference current generator sums the cell read currents to generate a sum current. Each of the sense amplifiers determines data state stored in each of the memory cells based on each of the cell read currents and an average current. The average current is obtained based on the sum current.
