The Korean electronics maker says its latest 2Gb (256MB) DDR3 chips consume 30% less power than 50nm parts, and can be produced at more than double the cost-efficiency. The 30nm technology also boosts productivity by 60% over 40nm DDR3 chips. The new chips run at 1.35V or 1.5V, and in a typical notebook, a 4GB DDR3 module is said to consume only three watts per hour.
This announcement comes a few months after Samsung revealed the world's thinnest multi-chip memory package. Measuring a mere 0.6mm in height, the package contains eight 30nm 32Gb NAND flash chips (32GB in total).
