ABSTRACT:
Some demonstrative embodiments of the invention include a method, device and/or system of selectively allowing a host processor to access a host-executable code. A host apparatus may include, for example, a host processor; and a protected memory module comprising: a memory to maintain a host-executable code to be executed by the host processor; and a memory controller to authenticate the host-executable code, and to selectively allow the host processor to access the host-executable code based on an authenticity of the host-executable code. Other embodiments are described and claimed.
