Abstract
A nonvolatile programmable logic circuit using a ferroelectric memory performs a nonvolatile memory function and an operation function without additional memory devices, thereby reducing power consumption. Also, a nonvolatile ferroelectric memory is applied to a FPGA (Field Programmable Gate Array), thereby preventing leakage of internal data and reducing the area of a chip.
Claims3
A nonvolatile programmable logic circuit comprising:
- a latch means having an output signal that changes according to input data when a clock signal and a first logic control signal are activated;
- a first nonvolatile ferroelectric register for generating the first logic control signal to selectively transmit the clock signal depending on a programmed code in a nonvolatile ferroelectric capacitor;
- and
- a second nonvolatile ferroelectric register for generating a second logic control signal to reset the latch means depending on a programmed code in a nonvolatile ferroelectric capacitor.
