Flash memory has many advantages over masked ROM for storing program code in security chips, such as smart cards. Flash memory offers greater protection against hardware and software attacks due to fundamental differences in the memory technologies. Flash also allows for faster and more economical upgrades to guard against new attacks. This paper addresses the differences between Flash memory and masked ROM memory as it relates to a security chip.
