Title: Innovations of Sungcheol Park

Introduction

Sungcheol Park is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and effectiveness of semiconductor devices.

Latest Patents

One of his latest patents is a logic built-in self-test (BIST) circuit and semiconductor device that includes this innovative circuit. This logic BIST circuit performs a scan test that improves test coverage for each clock domain. It features an OR gate that receives a scan enable signal and a register setting signal, generating a modified scan enable signal. Additionally, a clock gating circuit outputs an enable clock irrespective of a function enable signal when the register setting signal has a first logic value. The scan chain captures the output of a first logic circuit connected to flip-flops according to the enable clock.

Another notable patent involves a semiconductor integrated circuit designed to receive a test scan input, a test clock, and a test mode signal, ultimately outputting a secure scan output signal. This integrated circuit includes a secure key circuit that generates delay input signals, which are differently delayed from the test scan input. It also features a key comparator that generates a verification result indicating whether an input key of the input key signal matches a preset reference key. The chip generates a scan output signal based on the test scan input, while a scan output remapper obfuscates the scan output signal according to the verification result.
