Abstract
A semiconductor device and an operation method capable of operating with high reliability are provided. A voltage monitoring circuit () of the disclosure includes: a power-on detection part () configurated to detect whether a supply voltage (EXVDD) of an external power supply terminal has reached a power-on voltage level; a timer () configurated to measure a predetermined time when the power-on voltage level is detected; a through current generation part () configurated to generate a through current between the external power supply terminal and GND during a period when the timer () measures the predetermined time; and a power-off detection part () configurated to detect whether a drop of the supply voltage (EXVDD) has reached a power-off voltage level when the through current is generated.
