    摘要: A secure memory system and a method of maintaining the security of memory contents. One embodiment of the system includes: (1) a security control module configured to transmit a system memory secure mode signal and processor secure mode signal to place the system in a secure mode, (2) a secure memory bridge coupled to the security control and system memory and configured to encrypt and decrypt data associated with the system memory based on a state of the system memory secure mode signal and (3) a boot processor coupled to the security control module and the secure memory bridge and configured to transmit requests to the secure memory bridge in the secure mode and an unsecure mode.
