Latest Patents

One of Hattori's latest patents is a regulator circuit. This circuit includes a detection circuit that outputs a feedback voltage in accordance with an output voltage. It also features a reference voltage input section, a feedback voltage input section, and an operational amplification circuit that compares the reference voltage and feedback voltage. The output circuit supplies an output voltage based on the operational amplification circuit's output. Additionally, a connection/disconnection circuit connects or disconnects the output terminal of the detection circuit and the feedback voltage input section. The voltage setup circuit sets a predetermined voltage for the feedback voltage input section. In standby mode, the connection/disconnection circuit disconnects the output terminal from the feedback voltage input section, while the voltage setup circuit establishes a predetermined voltage.

Another notable patent is for a non-volatile semiconductor memory device. This device features a memory cell array with a group of memory cells capable of retaining two-bit information. Each memory cell consists of a pair of transistors with charge storage regions, mutually connected gates, and sources. Word lines are connected to the gates, while bit lines are linked to the sources and drains of the transistors. The bit lines connected to the drains of the transistors in a memory cell are linked to a comparison input terminal of a differential detector. The information retained in the memory cell is read based on the comparison result of current amounts inputted to the differential detector.
