Abstract
Provided is a semiconductor device which can perform secure data transmission/reception considering functional safety. The semiconductor device includes a hardware security module circuit which performs an authentication process and an error detection circuit used to perform an error detection process at least on first data which is processed in the hardware security module circuit. A memory area associated with the error detection circuit is configured to be accessible only by the hardware security module circuit when the error detection process is performed at least on the first data.
