Abstract
The disclosure includes a system and method of using a processor and protected memory. In a particular embodiment, the system includes a processor, a volatile memory accessible to the processor, and a first nonvolatile memory accessible to the processor. The first nonvolatile memory includes a first portion of memory that is protected and is readable when a shield bit indicates an unshielded mode of operation, but is unreadable when the shield bit indicates a shielded mode of operation and a second portion of memory that is unprotected and that is readable regardless of the value of the shield bit. The system includes a second nonvolatile memory including data to be transferred to the volatile memory.
