A secure memory card with encryption capabilities comprises various life cycle states that allow for testing of the hardware and software of the card in certain of the states. The testing mechanisms are disabled in certain other of the states thus closing potential back doors to secure data and cryptographic keys. Controlled availability and generation of the keys required for encryption and decryption of data is such that even if back doors are accessed that previously encrypted data is impossible to decrypt and thus worthless even if a back door is found and maliciously pried open.

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.
