Abstract
The invention considers a non-volatile semiconductor memory device comprising a first and second floating gate transistor, which are coupled in series. Each floating gate transistor comprises a floating gate. Programming means coupled to the first and second floating gate transistor are operable to place a selected electrical charge in one of the floating gates and less than the selected electrical charge in the other floating gate to represent either a first or second binary value.
