Abstract
Ferroelectric transistors are combined with MOSFETs to perform logic functions. The logic functions include a non-volatile ferroelectric latch (30), a clocked non-volatile ferroelectric latch (50), a programmable switch (60), an edge-triggered complementary flip-flop (78), a tri-state logic circuit (80), a ferroelectric logic NAND-gate (100), a clocked ferroelectric logic NAND-gate (140), and a programmable logic function (150). The programmable logic function (150) includes a programming terminal (156) to select between a NOR-gate function and a NAND-gate function.
