Abstract
A device includes first and second reference storage units, and first and second reference switches. The first reference switch outputs a first current at a first terminal thereof to the first reference storage unit. The first reference storage unit receives the first current at a first terminal thereof and generates a first signal, according to the first current, at a second terminal thereof to an average current circuit. The second reference switch outputs a second current at a first terminal thereof to the second reference storage unit. The second reference storage unit receives the second current at a first terminal thereof, and generates a second signal, according to the second current, at a second terminal thereof to the average current circuit. The first and second reference switches are coupled to a plurality of first memory cells by a first word line.
