Latest Patents

One of his latest patents is titled "Memory repair circuit using antifuse of MOS structure." This invention utilizes an antifuse of MOS structure to repair defective memory cells. The circuit is designed to construct antifuses using MOS transistors and program them effectively. It includes multiple antifuse devices that are programmed when a power voltage and a negative voltage are applied to their respective electrodes. Additionally, it features a latch that detects and latches the program states of the antifuse devices, along with a redundancy block that replaces defective cells with redundancy cells based on the latch's output.

Another significant patent is the "Repair circuit using antifuse." This circuit substitutes defective cells with redundancy cells. It comprises an antifuse that is programmed by a voltage difference, a programming circuit, and a detection circuit that determines whether the antifuse is programmed or unprogrammed. The detection occurs during or after the power stabilization period. The circuit also includes a latch that latches the detection result to generate an output signal, which is then used by a redundancy circuit to repair defective cells.
