Samsung's New LPDDR4 Mobile Memory Chip Paves Way for 4GB Smartphones

Regardless of which smartphone we test, it seems that memory bandwidth is always something of a concern or bottleneck. Even the world's most powerful smartphones could stand to benefit from more memory, particularly now that 64-bit processing has made its way to the mobile arena, and Samsung is well aware of that. So, in order to align the sides a bit better, the company has developed the industry's first 8Gb LPDDR4 mobile DRAM, which is fabricated using 20-nanometer process technology and offers 1GB on a single die.


The new chip should provide 50% higher performance than even the fastest LPDDR3 or DDR3 memory while consuming 40% less energy at just 1.1 volts. In addition, Samsung’s new 8Gb LPDDR4 uses a Low Voltage Swing Terminated Logic (LVSTL) I/O interface, which was originally proposed by Samsung to JEDEC and has become a standard specification for LPDDR4 DRAM. Based on this new interface, the LPDDR4 chip will enable a data transfer rate per pin of 3,200 megabits per second (Mbps), which is twice that of the 20nm-class LPDDR3 DRAM now in mass production.

With the new chip, Samsung will focus on the premium mobile market including large screen UHD smartphones, tablets and ultra-slim notebooks that offer four times the resolution of full-HD imaging, and also on high-performance network systems. What it could mean, in practical terms, is that super-phones with 4GB of inbuilt RAM aren't far out, and hopefully we'll see one or two teased at either CES or MWC over the next two months.
