Abstract

A method for portable device memory management includes determining an operational mode of a program configured to execute on the portable device based on validating the presence of one or more memory markers in the memory. The one or more memory marker includes a memory line having a predetermined length and including a data portion and a tag. The method also includes allowing one or more commands based on the operational mode and terminating execution of the program of at least one but less than a predetermined number of memory markers are validly present in the memory
