Nanochip uses one micron semiconductor fabs to make our MEMs chips. This type of equipment was used over ten years ago for most semiconductor products. Therefore, the cost of building a MEMs fab to make our chips is in the tens of millions of dollars, unlike the several billion dollars needed to make a 70 nm and soon a 45 nm semiconductor fabrication facility. Furthermore, we can use the same initial semiconductor/MEMS fab to make future generations of Nanochips since we have no requirements to change our lithography as we double density every year. The design is scalable to 1 Terabyte (TB) chips, according to Nanochip.
Another competing technology for future computer memory is programmable metallization cell (nanoionic)
Programmable-metallization-cell (PMC) memory, or nano-ionic memory could start replacing flash memory in 18 months (2009)
A new type of memory technology could lead to thumb drives or digital-camera memory cards that store a terabyte of information--more than most hard drives hold today. The first examples of the new technology, which could also slash energy consumption by more than 99 percent, could be on the market within 18 months
