A monolithic 8Gb DDR3 SDRAM chip is made available by Micron by using its 25nm memory chip process.
Micron's DDR3 portfolio includes 8Gb single-die and dual-die components, 32GB RDIMMs (dual rank), 64GB LRDIMMs, 32GB ECC SODIMMs and 16GB VLP ECC UDIMMs.
The top vendor of DRAM, Samsung had started mass production of 4-gigabit (Gb) DDR3 DRAM using new 20 nanometer process technology and immersion ArF lithography.
Micron, Samsung are going 3D now to increase memory density due to cost advantages.
Gartner finding on DRAM market says "global DRAM market will grow from $35.6 billion US dollars in 2013 to $37.9 billion US dollars in 2014."
