Samsung's new memory chips that have just gone into mass production for "next-generation" smartphones are designed to address battery consumption through increased efficiency. Thin phones are nice and all, but the longer battery life in high-end smartphones is even better.
Specifically, the second generation of 10nm (1y-nm) class 16Gb LPDDR4X (Low Power, Double Data Rate, 4X) Mobile DRAM chip achieves the current data rate of 4,266 Mbps seen in flagship smartphones, but does so with a power decrease that is up to 10 percent.
Things get even more interesting when Samsung combines the chips, creating an 8GB LPDDR4X mobile DRAM package using four of the 10nm LPDDR4X 16Gb DRAM chips (16Gb = 2GB). That might seem like a lot of inscrutable text, but the result is a package that is more efficient in terms of energy in general and 20 percent thinner than the current design.
The new energy efficiency chip "should first reach the market by the end of this year or the first part of 2019," said Sewon Chun, senior vice president of Sales and Marketing for Memory at Samsung Electronics. This move is a major change in the alignment of Samsung chips because it implies a 70 percent expansion in production. The new memory chips should arrive just in time for the new wave of Galaxy flagships, but apparently Note 9 will not arrive later this month.
