Latest Patents

One of his latest patents is a semiconductor device and operation method that features a power-on operation. This invention provides a semiconductor device capable of operating with high reliability. The voltage monitoring circuit includes a power-on detection part that detects whether a supply voltage of an external power supply terminal has reached a power-on voltage level. Additionally, it features a timer that measures a predetermined time when the power-on voltage level is detected. A through current generation part is also included, which generates a through current between the external power supply terminal and ground during the timer's measurement period. Furthermore, a power-off detection part is designed to detect whether the supply voltage has dropped to a power-off voltage level when the through current is generated.

Another notable patent is the power down detection circuit and semiconductor storage apparatus. This invention allows for the adjustment of a power down detection level while suppressing temperature dependence. The power down detection circuit consists of a bandgap reference (BGR) circuit, a trimming circuit, a resistance division circuit, and a comparator. The BGR circuit generates a reference voltage based on the supply voltage, while the trimming circuit adjusts this reference voltage based on a trimming signal. The resistance division circuit generates an internal voltage lower than the supply voltage, and the comparator detects when this internal voltage is lower than the reference voltage for power down detection, subsequently outputting a reset signal.
