I think Buggi's post is pretty much consistent with what I wrote recently:

4bit ORNAND < 2 bit (MLC) NAND < 2 bit (Mirrorbit) NOR < 1 bit NAND < 1 bit NOR
"

To make it more precise:

DIE size
- 4bit ORNAND node + 1/2 node = 2 bit (MLC) NAND node
- e.g. 65nm NOR = 53-55nm NAND

- 2bit ORNAND node - 1/2 node = 2 bit (MLC) NAND node
- e.g. 45nm NOR = 53-55nm NAND

or:

NAND 2b/c needs 37-38nm to equal Quad 45nm SPSN-NOR
or
NAND 2b/c needs 53-55nm to equal Quad 65nm SPSN-NOR
or
NAND 2b/c needs 71-73nm to equal Quad 90nm SPSN-NOR
