Abstract:
In an embodiment of the present invention, a processor includes content storage logic to parse digital content into portions and to cause each portion to be stored into a corresponding page of a memory. The processor also includes protection logic to receive a write instruction having a destination address within the memory, and if the destination address is associated with a memory location stores a portion of the digital content, erase the page associated with the memory location. If the destination address is associated with another memory location that does not store any of the digital content, the protection logic is to permit execution of the write instruction. Other embodiments are described and claimed.
