Abstract
In one embodiment, a peripheral controller coupled to a processor can include a storage controller. This storage controller can control access to a non-volatile storage coupled to the peripheral controller. The storage may include both secure and open partitions, and the storage controller can enable access to the secure partition only when the processor is in a secure mode. In turn, during unsecure operation such as third party code execution, visibility of the secure partition can be prevented. Other embodiments are described and claimed.
