Title: Innovations of Ling-Yueh Chang
Introduction
Ling-Yueh Chang is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of memory technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of resistive type memory devices.
Latest Patents
One of his latest patents is a "Read/write control device of resistive type memory." This invention includes a first logic unit and a second logic unit, which are integral to a bit line driving circuit. The first logic unit connects to a gate of a first transistor set, which outputs a bit line signal. This transistor set consists of one PMOS and one NMOS connected in series. The first logic unit receives a column selection signal and a control signal that determines if data '0' is to be written. Additionally, in the source line driving circuit, the second logic unit connects to a gate of a second transistor set for outputting a source line signal, also comprising one PMOS and one NMOS in series. This unit similarly receives a column selection signal and a control signal for writing data '1'.
Another significant patent is the "Split control pad for multiple signal." This innovation involves a control pad divided into two sections, capable of outputting one of three signals: 00, 01, or 11 on an integrated circuit. Each section connects to different voltage sources, such as Vdd for logical '1' and Vss for logical '0', establishing a default output of 1,0. When bonded with external Vdd or Vss, the sections can output "1,1" or "0,0," allowing for versatile logic word combinations for integrated circuits.
