Remember that memristors are going to reinvent computer memory by 2014? (speed and power near dynamic RAM, but nonvolatile) When the storage hierarchy gets retuned you may find all of your device's nonvolatile storage in your address space. Or maybe not. http://en.wikipedia.org/wiki/Resistive_random-access_memory http://en.wikipedia.org/wiki/Resistive_random-access_memory Beyond that… The ARM 64 bit comes with 31 64 bit registers instead of 14 32 bit registers. There are a number of instruction set differences, such that you run the same object code on previous architectures. The NEON unit also gets twice the registers, double precision floating point, and IEEE 754 compliance.
