Title: Koudoh Yamauchi: Innovator in Semiconductor Technology
Introduction
Koudoh Yamauchi is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to integrated circuits.
Latest Patents
Yamauchi's latest patents focus on semiconductor integrated circuits that incorporate nonvolatile memory and logic circuits. These circuits utilize information stored in the nonvolatile memory to perform logical operations. The nonvolatile memory consists of bit lines, word lines, and memory cells. Each memory cell is made up of MOS transistors, with gate electrodes connected to a word line. Information storage is determined by whether one source/drain electrode of the MOS transistors is connected to a source line or left floating. During periods outside a predetermined access time, the potential difference between the source/drain electrodes of the MOS transistors is zeroed, effectively preventing subthreshold leakage current from passing through the memory cell while in standby mode. During the designated access period, a potential difference is generated between the source/drain electrodes, allowing the bit line potential to be varied through word line selection.
