Title: Hajime Nagao: Innovator in Storage and Semiconductor Devices
Introduction
Hajime Nagao is a prominent inventor based in Nagasaki, Japan. He has made significant contributions to the field of storage and semiconductor devices. With a total of 4 patents to his name, Nagao's work has had a considerable impact on technology.
Latest Patents
Nagao's latest patents include innovative designs for storage devices and semiconductor devices. One of his patents describes a storage device that features a memory cell with a storage element capable of changing its resistance value. This change occurs when a voltage equal to or higher than a first threshold voltage is applied, transitioning from a high resistance state to a low resistance state. Conversely, it can revert to a high resistance state when a voltage equal to or higher than a second threshold voltage, which differs in polarity from the first, is applied. The patent outlines the relationship between resistance value, threshold voltage, and current during the erasure process.
Another patent focuses on a storage device that includes a storage element with characteristics that allow its resistance value to change from high to low and vice versa, based on applied electrical signals. This design incorporates a circuit element connected in series with the storage element, forming a memory cell arranged in a matrix. The resistance values of the circuit element differ when the storage element is read compared to when it is written or erased.
