Latest Patents
Hisashi Shima's latest patents include a gas sensor and a variable resistance non-volatile memory element. The gas sensor features a gas-sensitive body layer that includes a metal oxide layer, with electrodes designed to detect gas presence. This innovative sensor exhibits a resistance change characteristic that allows it to transition between high and low-resistance states based on applied voltage. Notably, the gas-sensitive body layer's resistance decreases when it comes into contact with hydrogen-containing gases.
The variable resistance non-volatile memory element consists of first and second electrodes with a variable resistance layer in between. This layer can reversibly change its resistance value based on electrical signals. It includes a first variable resistance layer made of an oxygen-deficient metal oxide and a second layer that is a composite oxide with a different degree of oxygen deficiency. This design enhances the performance of memory devices, making them more efficient.
