Title: The Innovations of Yoshihide Bando
Introduction
Yoshihide Bando is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 8 patents. His work focuses on improving the efficiency and reliability of voltage supply circuits and semiconductor memory systems.
Latest Patents
One of his latest patents is a voltage supply circuit for semiconductor devices. The purpose of this invention is to decrease the leak current of a voltage supply circuit using a MOS transistor. This circuit comprises an n-channel MOS transistor with a low threshold voltage, connected to the power supply voltage, and a p-channel MOS transistor that supplies voltage to a load circuit. By applying a voltage of V gs=1 V to the gate-sources of the p-channel MOS transistor during standby, it operates in a larger cut-off region, enhancing efficiency.
Another notable patent involves a semiconductor memory that features dummy regions within the memory cell array. This design partitions the memory cell array into multiple regions, each containing several sense amplifiers. Dummy regions are formed between these memory regions, incorporating dummy bit lines set to a predetermined voltage during operation. This configuration prevents voltage changes in one memory region from affecting adjacent regions, thereby reducing the risk of malfunctions in semiconductor memories.
