Title: Innovations of Hideaki Uemura
Introduction
Hideaki Uemura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of nonvolatile memory technology. With a total of 6 patents to his name, Uemura's work has had a lasting impact on the industry.
Latest Patents
One of Uemura's latest patents is a voltage generator for nonvolatile memory. This invention generates an applied voltage to be applied to nonvolatile memory. It includes a first voltage generator that produces a first voltage corresponding to the applied voltage, a reference voltage generator, and a comparator. The comparator compares the first voltage with the reference voltage and outputs a boost operation control signal based on the comparison result. The booster then generates the applied voltage in a pulse-like voltage waveform by starting or stopping boost operation according to the control signal. The applied voltage can be varied within one pulse-like voltage waveform by adjusting either the first voltage or the reference voltage.
Another notable patent is the master-slave type flip-flop circuit. This circuit includes a master input transfer gate connected to the input of a master latch portion and a slave input transfer gate connected to the input of a slave latch portion. A clock generating circuit provides both inverted and non-inverted clock signals to the slave input transfer gate. The design utilizes two inverters to reduce the area of the master-slave flip-flop circuit, allowing for a more compact design.
