Abstract:
A majority calculation semiconductor device comprising:a charge transfer channel to one end of which electric charges supplied from a charge supply unit are input, and which includes a plurality of branching regions at an intermediate portion; an insulated reset gate electrode provided on one of said branching regions; independent insulated gate electrodes, each independent insulated gate electrode being provided on the corresponding one of the other branching regions; an insulated transfer electrode, provided on a common region of said charge transfer channel, for transferring the electric charges in a predetermined direction within said charge transfer channel; a conversion unit adapted to convert the transferred electric charges into a voltage which corresponds to the combined charges; and a resettable sense amplifier unit to which an output signal from said conversion unit is input and which produces outputs corresponding to said voltage following each resetting thereof; and wherein input signals are input to said independent insulated gate electrodes so that the charges corresponding to said input signals are transferred to said common region.
