Abstract: A semiconductor device includes a processor unit, a memory storing a boot program, a reset controller and an address check unit. The reset controller controls a reset for the processor unit based on a reset request and outputs a boot address for the boot program to be executed after reset release to the processor unit. The address check unit performs a tampering check for the boot address output from the reset controller and outputs a boot address error signal based on a tampering check result.
