> From the outset these new memory chips are said to offer improved data rates and power efficiency over the previous 20nm-class memory chips. The new DRAM is capable of 30 per cent better performance, supporting data rates up to 3,200Mbps. Energy consumption benefits are also evident, but not quite as good, with 10 to 20 per cent less power consumed by the new chips. Samsung says it leveraged proprietary cell design technology, QPT (quadruple patterning technology) lithography, and ultra-thin dielectric layer deposition technology to produce the new chips.
