Abstract
A nonvolatile memory device comprising first and second transistors connected between respective first and second terminals and a reference potential terminal, the transistors having first and second floating gates, respectively, for storing complementary charges. The device further comprises first and second input lines capacitively coupled to the gates, and means for providing a biasing voltage slightly in excess of the threshold voltage of the transistors to the input lines.
