Semiconductor devices including E-fuse arrays

摘要

The semiconductor device includes a start signal generation circuit and a boot-up operation circuit. The start signal generation circuit detects a level of an external voltage signal to generate a pre-detection signal; executes a differential amplification operation of a voltage difference between the external voltage signal and a reference voltage signal to generate a first detection signal; detects a level of an internal voltage signal to generate a second detection signal, and generates a start signal in response to the first and second detection signals. The boot-up operation circuit executes a boot-up operation in response to the start signal.
