NAND scaling already has some serious problems... as the NAND cell shrinks, doing 4b and 3b MLC is becoming much more difficult... Notice that IMF is doing just 2b MLC... Without some breakthroughs in error correcting codes for NAND, we are probably very near the end of NAND scaling (i.e. while it might be technically possible to scale NAND, there will be no economic benefit to scaling NAND)

Spansion/AMD asymmetric charge trap flash technology does not work at sub 40nm... ask Dr. Hwang, the former CEO of Samsung...

Big question: How long will NAND scale?

My wild guess: 1) I think IMFT will do a die shrink. 2) That will get them to the 21- or 22-nm node. 3) Then, they will do 16-nm or so. Another guess: Over time, I see them doing a charge-trap technology. In doing so, they will buy Spansion to gain the IP. This will give them 16-nm, 12-nm, etc. Long term? I see 3-D, maybe phase-change...

Does I-M plan to push NAND below 20 nm or will they change to an alternative memory in two years?

This from a reader:

I will be watching how fast the ability to make these chips moves to China.

It's 8 GB, i.e. 64 Gb.

Mark It looks like something is wrong with your numbers. 167mm2 for an 8Gb MLC Flash is way too big for 25nm technology. Please comment? Thanks Scott

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
