摘要：
A method for dynamically (i.e., upon boot) rewriting, in a failure resistant manner, of part of, or the entirety of, the flash memory for a device allows for a changing of location for logical blocks of execute-in-place code. Conveniently, the rewriting results in a randomization, of varying degree, of the address space layout upon each boot up cycle.
