Abstract
Programmable logic gate structures employ pairs of complementary transistors. Programming of the transistors is accomplished either by voltage biasing a shared floating gate of a CMOS transistor pair or by providing a variable resistance serially or in parallel with each transistor. The variable resistance can be a fusible link or a semiconductor device having an alterable crystalline structure.
