Title: Kohji Shimbayashi: Innovator in Semiconductor Technology
Introduction
Kohji Shimbayashi is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work has been instrumental in advancing memory devices and programmable logic devices.
Latest Patents
One of his latest patents is for a semiconductor memory device. This device features a plurality of memory cells from which cell data is read out based on at least one control signal. It includes a transfer gate that receives read data from one of the memory cells, a latch circuit that latches the read data, and an output buffer that outputs data based on the latched read data. Additionally, the memory device has a transfer gate controller that produces a latch control signal to manage the ON/OFF action of the transfer gate, incorporating a delay circuit to control level-switching timing.
Another significant patent is for a programmable logic device that includes a verify circuit for a macro-cell. This device comprises an input/output buffer, a logic array, and switches for altering the logic operation. The switching operations are determined by data stored in non-volatile memory elements arranged in a matrix. The contents of these memory elements are read out and stored in registers, which then control the switches.
