Title: The Innovative Mind of Duk-Ha Park: Pioneering Memory Device Technology

Introduction

Duk-Ha Park, a prominent inventor based in Suwon-si, South Korea, has made significant contributions to the field of memory devices. With a remarkable portfolio of 15 patents to his name, Park has continuously pushed the boundaries of innovation in memory technology.

Latest Patents

Among his latest patents is the "Method of refreshing memory using multiple operating voltages and memory device performing the same." This invention describes a memory device equipped with memory cells that function in three distinct modes: a normal mode, a first self-refresh mode, and a second self-refresh mode. The first self-refresh mode allows for data retention without an external command, effectively reducing the time needed to revert to normal operation. In contrast, while the second self-refresh mode also facilitates data retention, it takes longer to return to the normal mode. Notably, the normal mode supplies higher operating voltage to the memory cells than the second self-refresh mode, showcasing Park's innovative approach to memory management.
