can someone explain to me wat a NAND is? i see these NAND installers and uninstallers but i dont even no wat they are. thanks

NAND is the kind of chipdesign mostly used for creating flash-memory, memory that does not need power to hold its contents.

The Wii's internal memory is of that kind. "NAND" became the synonym for the Wii's internal memory, especially when it is accessed in raw form, without the aid of any helper function (from Nintendo).

To add to that, we use the term NAND because the Wiis NAND is made up of tons of NAND logic gates. A NAND (or Not AND) logic gate is an electronic gate that outputs a high when at least one of its inputs are low, and outputs a low only when all of its inputs are high.

nope, that would make it undefined when one input is high and the other is low.

The truth table for NAND is:

A      B      NAND(A,B)
-------------------------
F      F            T
T      F            T
F      T            T
T      T            F

(sorry for being pedantic :) )

Ah, you're right. I type too fast :P I've edited my original comment.

High's and Low's, on's and off's....bloody binary!!!! (Tears a little hair out)

NAND flash memory is not actually based on NAND logic gates, but NAND flash cells act like NAND gates. There is also NOR flash, by the way.
