Title: Sook Kyung Kim: Innovator in Flash Memory Technology
Introduction
Sook Kyung Kim is a prominent inventor based in Icheon, South Korea. She has made significant contributions to the field of flash memory technology, holding a total of 3 patents. Her innovative approaches have enhanced the efficiency and reliability of flash memory devices.
Latest Patents
Sook Kyung Kim's latest patents include a program method of flash memory devices and an erase method of flash memory devices. The program method involves a technique for erasing and programming flash memory devices that include multi-level cells (MLCs). In this method, specific MLCs of a word line are selected, and some are pre-programmed based on their individual threshold voltages. The selected MLCs are pre-programmed with a first voltage, while the remaining MLCs are prohibited from pre-programming. Subsequently, the remaining MLCs connected to the selected word line are programmed by applying a second voltage that gradually rises from the pre-program voltage.
The erase method focuses on improving program speed by pre-programming MLCs to reduce the voltage range in which their threshold voltages are distributed. This approach minimizes the fail occurrence ratio during the erasing process, enhances the threshold voltage distribution of MLCs, and shortens the overall program time in subsequent operations.
