NONVOLATILE LOGIC CIRCUIT, INTEGRATED CIRCUIT INCLUDING THE NONVOLATILE LOGIC CIRCUIT AND METHOD OF OPERATING THE INTEGRATED CIRCUIT

摘要

PURPOSE: A nonvolatile logic circuit, an integrated circuit including the nonvolatile logic circuit and a method of operating the integrated circuit are provided to stably drive a nonvolatile logic circuit by performing wiring data in a pair of nonvolatile memories only when an write enable signal is activated. CONSTITUTION: In a nonvolatile logic circuit, an integrated circuit including the nonvolatile logic circuit and a method of operating the integrated circuit, a latch unit(11) has a pair of latch nodes. A pair of nonvolatile memory cells(12,13) perform wiring different data. A pair of nonvolatile memory cells receives first and second write voltage which are different. A general operation selection unit(14) prevent first and second nonvolatile memory cell from being connected to the latch unit. A read operation selection unit(15) applies data stored in the nonvolatile memory cell to the first and second latch nodes. A write operation selection unit(16) applies first and second write voltage which are different to the first and second nonvolatile memory cell. An equalizer(17) equalize the voltage of the first and second latch node.
