Title: Hee Jun Kim: Innovator in Calibration and Memory Devices

Introduction

Hee Jun Kim is a prominent inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of electronics, particularly in the development of calibration devices and memory technologies. With a total of 11 patents to his name, Kim's work has had a substantial impact on high-speed data operations under low power conditions.

Latest Patents

Among his latest patents is a calibration device designed for high-speed data input/output operations while maintaining low power consumption. This device is coupled to a communication line shared by multiple devices. It performs an iterative eye width scanning by adjusting a set voltage level from a first voltage level to a reference center voltage level. The first voltage level corresponds to a cross point where the values of signals or data transmitted via the communication lines change in different directions. The device determines a zero crossing for the signals or data by identifying the voltage level corresponding to the largest value among a plurality of eye widths obtained through the iterative scanning.

Another notable patent is a reference voltage training circuit and semiconductor apparatus that includes this circuit. The reference voltage training circuit consists of a normal buffer that generates a first received signal by receiving one of the differential signals based on the other. It also includes a calibration signal generation circuit that produces a second received signal according to a reference voltage and generates reference voltage calibration signals by comparing the phases of the two received signals. This innovation allows for the calibration of the reference voltage level according to the generated calibration signals.
