ABSTRACT:
A computer system includes a processor which may initialize a secure execution mode by executing a security initialization instruction. Further, the processor may operate in the secure execution mode by executing a secure operating system code segment. The computer system also includes a system memory configured to store data in a plurality of locations. The computer system also includes a memory controller which may selectively clear the data from a programmed range of the memory locations of the system memory when enabled in response to a reset of the processor.
