Abstract
A memory system comprises an encryption engine implemented in the hardware of a controller. In starting up the memory system, a boot strapping mechanism is implemented wherein a first portion of firmware when executed pulls in another portion of firmware to be executed. The hardware of the encryption engine is used to verify the integrity of at least the first portion of the firmware. Therefore, only the firmware that is intended to run the system will be executed.
