Latest Patents

One of Jin-Keun Oh's latest patents is a "Memory repair circuit using antifuse of MOS structure." This invention utilizes an antifuse of MOS structure to repair defective cells by constructing the antifuse with MOS transistors and programming the antifuse circuit appropriately. The memory repair circuit consists of multiple antifuse devices, each programmed when a power voltage and a negative voltage are supplied to their respective electrodes. It also includes a latch for detecting and latching the program states of the antifuse devices, along with a redundancy block that replaces a defective cell with a redundancy cell based on the latch's output.

Another significant patent is the "Repair circuit using antifuse." This repair circuit substitutes a defective cell with a redundancy cell. It includes an antifuse programmed by a voltage difference across its terminals, a programming circuit for the antifuse, and a detection circuit that determines whether the antifuse is programmed or unprogrammed. This detection occurs during or after a power stabilization period. The circuit also features a latch circuit that latches the detection result to generate an output signal, and a redundancy circuit that repairs the defective cell in response to this output.
