Well I was counting on NAND flash. That's how are getting more transistors per chip with them. The memory cells have basically stopped shrinking in NAND and actually got bigger when we first started to stack them. FinFETs effectively lets us pack transistors closer. This is because much of the structure of a transistor is in a 3D fin that sticks out of the wafer. By making the fin taller, you can pack the transistors even closer. But it can be argued that by volume, transistors are basically the same size. GAAFETs lets us go even further with this idea.
