Abstract

A difference calculating neural network is disclosed having an array of synapse cells arranged in rows and columns along pairs of row and column lines. The cells include a pair of floating gate devices which have their control gates coupled to receive one of a pair of complementary input voltages. The floating gate devices also have complementary threshold voltages such that packets of charge are produced from the synapse cells that are proportional to the difference between the input and voltage threshold. The charge packets are accumulated by the pairs of column lines in the array.
