Latest Patents

Kawasaki's most notable patent is an "Apparatus for compensating for radiation resistance of semiconductor memory." This invention aims to improve the radiation tolerance of semiconductor memory by incorporating three main components: a voltage value acquisition unit that calculates the maximum data retention voltage at which data can be inverted under reduced power supply conditions, a correction value determination unit that establishes a voltage correction value based on the difference between the retention voltage and a reference voltage, and a voltage adjustment unit that modifies either the power supply voltage or substrate bias voltage based on the calculated correction value. This innovation is crucial for ensuring the reliability of semiconductor memories in radiation-prone environments.

In addition to this, Kawasaki has also patented a "Semiconductor device" featuring an array of phase-locked loops (PLL) that work in sync with a common reference clock signal to produce multiple clock signals. These clock signals undergo a majority operation to generate a predominant clock signal, facilitated by a filter circuit functioning as a low-pass filter. This invention enhances the robustness and stability of semiconductor operations, making it a significant advancement in the field.
