Latest Patents

Ohtsuka holds a patent for a nonvolatile memory that achieves high device reliability and efficiency. The technology involves applying a predetermined bias voltage between a source and a drain to change a gate voltage. This process allows a current to flow discretely between the source and the drain, in accordance with quantized electrostatic energy levels in an island electrode. The switching ON/OFF of the current is enabled by applying half-electron charge to a gate. When the gate voltage induces polarization in a ferroelectric layer, its electric field is applied to the island electrode. This innovation allows for high sensitivity in measuring the current between the source and the drain. Additionally, charge holding is facilitated by the polarization in the ferroelectric layer, ensuring that stored data remains intact even when the power supply is cut off. Ohtsuka has 1 patent to his name.
