Abstract
A secure memory and processing system is disclosed for use in various types of communication devices. The secure processing system provides for the encryption and storage of sensitive data in a storage medium external to the secure processing system. The encrypted data is decrypted with encryption logic circuitry within the secure memory and transferred to a zeroizable memory for use by a host processor. The secure memory uses a laser-scribed encryption key coupled to encryption logic circuitry within the secure memory for encrypting and decrypting the sensitive information.
