"Our primary operating expense investments in 2011 will be in research and development, and we will include Fab 5 start up costs, as well as technology investment in [10nm-class] NAND and beyond," said Judy Bruner, chief financial officer of SanDisk Corp., during a conference call with financial analysts.
SanDisk notes that the demand towards flash memory is growing rapidly thanks to the increase of mobile devices' popularity. As a result, SanDisk, which co-operates NAND flash manufacturing capacity with Toshiba Corp. has to accelerate production of two-bits-per-cell and three-bits-per-cell types of multi-level-cell (MLC) flash memory.

So here's the MLC math:
45nm=10,000 write cycles
25nm=2,000 write cycles
So what do you think the cycles will be for 10nm? Yep, 400. So you quadruple the cells per a given space, but you reduce their lifespan by 80% or 1/5. The math just doesn't support the shrinking bringing down prices. In fact it would probably increase the prices.
