SEMICONDUCTOR DEVICES INCLUDING E-FUSE ARRAYS

Semiconductor devices are provided. The semiconductor device includes a voltage generation control circuit, a read voltage generator, and a control data storage unit. The voltage generation control circuit generates a voltage control signal enabled during a boot-up operation and disabled after the boot-up operation. The read voltage generator generates a read voltage signal in response to a read signal and the voltage control signal. The control data storage unit executes the boot-up operation in response to the read voltage signal, a row address signal and a column address signal to transmit control data to a first data latch unit and a second data latch unit.
