Introduction

Wei-Sung Chen is a notable inventor based in Hsinchu County, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work primarily focuses on enhancing electronic circuit designs and non-volatile memory technologies.

Latest Patents

One of his latest patents is an electrostatic discharge protection circuit. This ESD protection circuit includes a buffer circuit, a driving circuit, and a power-clamping circuit. The buffer circuit consists of first and second transistors with a first conductivity type, arranged in a cascade configuration between a first node and a first power supply node. A bonding pad is connected to the first node, while the drive circuit determines the state of at least one of the first and second transistors based on a control voltage. The drive circuit features a third transistor with a second conductivity type, which is linked between a second power supply node and the gate of the first transistor, controlled by a control signal. The power-clamping circuit connects the bonding pad and the gate of the third transistor at a second node, with the control voltage generated at the second node based on the voltage at the bonding pad.

Another significant patent by Chen involves a non-volatile memory cell and methods for programming, erasing, and reading it. This non-volatile memory cell comprises a well region with a first conductive type. It includes a first transistor and a second transistor, both having a second conductive type, positioned on the well region. The first gate of the first transistor is coupled to the second gate of the second transistor, and they share a drain region connected to a bit line. The first source region of the first transistor and the second region of the second transistor are linked to a first select line and a second line, respectively. Bits are stored in the first and second gates by controlling the select lines, and they can be erased by manipulating either line.
