DRAM maker Inotera has started shifting its entire production to the 50nm stack process.

According to Digitimes the outfit is planning to start with producing 10,000 wafers a month at its 12-inch fab from April. If the supply of coffee holds out, it will convert all of its capacity (130,000 wafers/month) to the more advanced node by Christmas.

Inotera is a big fan of Micron Technology's 50nm design. It has already increased production of 1Gb DDR2 chips based on the technology.  It has sent samples of 50nm-made 2Gb DDR3 to customers for verification.

It is keen to shift to the technology which means that it should be able to slash its production costs by half. The bonus to this is that DRAM prices are on the up so Inotera can coin in the profits.
