Abstract

This disclosure includes a method for securing a memory of an electronic system that includes initializing the memory, creating a security key, transmitting the security key to memory, storing the security key in the memory, transmitting the current security key and a new security key to the memory by the memory controller. If the current security key transmitted is the same as the security key stored in memory, then access to the memory is enabled and the current security key in the memory is replaced with the new security key. If the current security key transmitted is not the same as the security key stored in the memory, then access to the memory is disabled.
