...that eventually system main memory will become nonvolatile Nonvolatile memory is generally slower than volatile. In DRAM for example, the electrons need to be pushed just hard enough to charge a capacitor, that is to say they need to be pushed across the insulation layer between the two plates of a capacitor. A typical non volitile memory uses a diode to keep the charge. The signal must then be pushed backwards through the diode where they charge up a capacitor. This takes a higher voltage and more time. There is a fast solution, low voltage static ram which can keep its gates charged with a small battery. This is fast enough (even faster than DRAM) but it has many more transistors per bit so the chips tend to hold less memory. TP
