If you thought 2GB or 3GB of RAM in your smartphone was enough, Samsung disagrees. They have just announced on their blog today that they are now mass-producing the "industry's most advanced" 4-gigabit DDR3 RAM memory which is based on the new 20-nanometer process. The new memory will be available for mobile devices and PC's later on in 2014. Samsung did confirm that some of their upcoming mobile devices will be getting the new chips. But I think it's a safe bet to say that the Galaxy Note 4 is likely to get it. "Samsung's new energy-efficient 20-nanometer DDR3 RAM will rapidly expand its market base throughout the IT industry including the PC and mobile markets, quickly moving to mainstream status," stated Samsung Electronics Executive Vice President of Memory sales and marketing Young-Hyun Jun. He also stated "Samsung will continue to deliver next-generation DRAM and green memory solutions ahead of the competition, while contributing to the growth of the global IT market in close cooperation with our major customers."
Samsung says the new chip is now 25% more energy efficient than 25-nanometer memory. Samsung also says that they improved manufacturing productivity by 30% compared to the previous models. Samsung is also talking about the way it's actually making the new memory chips. "Samsung has pushed the envelope of DRAM scaling, while utilizing currently available immersion ArF lithography, in its roll-out of the industry's most advanced 20-nanometer 4-gigabit DDR3 RAM," they also stated, "with DRAM memory, where each cell consists of a capacitor and a transistor linked to one another, scaling is more difficult than with NAND flash memory in which a cell only needs a transistor. To continue scaling for more advanced DRAM, Samsung refined its design and manufacturing technologies and came up with a modified double patterning and atomic layer deposition."
So how about 4GB of RAM on your next Samsung smartphone, or just your next smartphone? Considering we're seeing laptops and desktops with close to 16GB and 32GB of RAM these days, I don't think it's all that surprising to see Samsung pushing out 4GB DDR3 RAM modules. What do you think?
