Abstract
An integrated circuit device that includes a secure or protected memory component is herein disclosed and enabled. The integrated circuit may be a wireless communication device or a smart card or an USB device. Additionally, the integrated circuit may be part of or in a computing device or mobile device. The integrated circuit device includes a private memory section for storing protected data that is not accessible by a user at the private memory section, but is accessible by a memory controller included in the integrated circuit device. The memory controller accesses the protected data with a combination of security operations that may include cryptography. The integrated circuit device may further include a wireless component for establishing a wireless connection with wireless computing devices or readers for wirelessly transmitting the protected data accessed by the memory controller to the wireless computing devices.
