Title: Seung Keun Lee: Innovator in Flash Memory Technology

Introduction

Seung Keun Lee is a notable inventor based in Yongin-si, South Korea. He has made significant contributions to the field of flash memory technology, holding two patents that showcase his innovative approach to enhancing memory devices.

Latest Patents

One of his latest patents is titled "Flash memory device having efficient refresh operation." This invention provides a flash memory device capable of efficiently performing a refresh operation. The device includes a normal memory array with a matrix of word lines and bit lines, where the memory cells are divided into blocks that are programmable and erasable. A refresh address generation unit generates a refresh block address that increases sequentially in response to a refresh driving signal. This design allows for efficient refresh operations to mitigate data disturbances.

Another significant patent is "Serial flash memory device and precharging method thereof." This invention describes a serial flash memory device where a single local bit-line data is sensed in synchronization with a clock. The method involves precharging multiple local bit-lines in sync with a first clock and disprecharging one of them in sync with a second clock. This approach eliminates coupling noise effects and secures time for precharging and sensing operations, improving upon prior methods.
