Introduction

Sung Yong Lim is a prominent inventor based in Uiwang-si, South Korea. He has made significant contributions to the field of memory devices, holding a total of 6 patents. His work focuses on enhancing the efficiency and reliability of memory systems.

Latest Patents

One of his latest patents is a memory device designed to prevent the generation of under-programmed memory cells. This innovative memory device includes a memory block, a peripheral circuit, and control logic. The memory block consists of multiple pages connected to various word lines. The peripheral circuit is responsible for executing a program loop that involves applying a program voltage to a selected word line and conducting a verify operation. This operation applies a verify voltage corresponding to the program voltage to the selected word line while applying a verify pass voltage to unselected word lines. The control logic plays a crucial role in adjusting the level of the verify pass voltage based on the threshold voltages of memory cells.

Another notable patent involves a memory device and its operating method. This invention features a memory block that includes first select transistors, memory cells, and second select transistors, which connect bit lines to a source line. A precharge controller monitors the program operation of the memory cells and adjusts the precharge mode of unselected strings based on the monitoring results. Additionally, a select line voltage generator produces either a positive or negative voltage applied to the second select line, depending on the precharge mode selected.
