Food for thought (based on a 1/4" X 1/4" memory area,
where cell size = F*L^2). Also, note that Samsung is
already in limited production @ .12um:

   
  L	F	cell size	cells		Mcells		Mbits/chip	Gbytes per computer
		(um^2)		per um^2	per chip 	@ 3bits/cell	@ 3 DIMMs per mobo
										& 16 chips per DIMM
.25	12	0.75		1.33		53.7		
.18	12	.389		2.57		103
.18	6	.194		5.14		207		621		3.7
.18	4	.130		7.72		311		933		5.6	
.18	2	.0648		15.4		622		1866		11.2
.12	6	.0864		11.6		466		1400		8.4
.12	4	.0576		17.4		700		2100		12.6
.12	2	.0288		34.7		1400		4200		25.2


If the cache area on a cumine is 20mm^2, then at F=4
and L=.12um (not too far off, IMO), you could fit
43MBytes (129MBytes w/3bits/cell) of OUM on the die.
