Title: Yejin Park - Innovator in Non-Volatile Memory Devices

Introduction

Yejin Park is a talented inventor based in Suwon-si, South Korea. She has made significant contributions to the field of semiconductor technology, particularly in non-volatile memory devices. Although she currently holds no granted patents, her innovative ideas are reflected in her latest patent applications.

Latest Patent Applications

Yejin Park's latest patent applications include two notable inventions. The first is titled "NONVOLATILE MEMORY DEVICE REDUCING A NUMBER OF PROGRAM BIT LINES AND PROGRAM METHOD THEREOF." This invention describes a method for programming a non-volatile memory device that involves executing a first program loop followed by a second program loop. In the first loop, a first program voltage is applied to a word line based on bit lines of first memory cells programmed to a first target state, which are set to an inhibitory bit line voltage. The second loop applies a second program voltage based on the bit lines of the first memory cells being set to a program bit line voltage.

The second application is for a "VERTICAL MEMORY DEVICE." This semiconductor device includes a lower circuit pattern on a substrate, a common source plate (CSP) on the lower circuit pattern, and a channel connection pattern on the CSP. It also features a sacrificial layer structure, a support layer, and first and second gate electrode structures. The design allows for a first channel that extends through the first gate electrode structure, the support layer, and the channel connection pattern, along with a contact plug that connects electrically to the lower circuit pattern.

Conclusion

Yejin Park is an emerging inventor whose work in non-volatile memory devices showcases her innovative spirit and technical expertise. Her latest patent applications reflect her commitment to advancing semiconductor technology.
