I just wanted to add (since I forgot to make it clear in my original message) that none of these storage places are truly non-volatile. If one cuts the power to the CUDA chip or the SRAM chip the PRAM settings and the NVRAM contents (respectively) will be lost. These storage areas achieve "non-volatile" status by virtue of the motherboard battery. Without the battery or the trickle from the power supply, their contents evaporate. Which is why unplugging the machine and removing the battery for several hours is a useful troubleshooting technique. Chips such as ROMs, EPROMs, EEPROMs and Flash Memory truly are non-volatile (retain their contents without power) but they are slower and more difficult (or impossible) to write to.
