Samsung Starts Producing 8Gb Mobile LPDDR4 DRAM

Electronics giant Samsung is pushing the DRAM envelope once again. The company has just started mass producing what is indeed the industryEUs first 8 gigabit (Gb), low power double rate 4 (LPDDR4) mobile DRAM (dynamic random-access memory). If you think thatEUs a mouthful, wait until you hear what it can do.

Samsung is building the next-generation DRAM based on its 20-nanometer process technology. As for LPDDR memories, itEUs the most widely used EUworking memoryEU for mobile devices in the world because it allows for smaller designs that use less power.

EUBy initiating production of 20nm 8Gb LPDDR4, which is even faster than the DRAM for PCs and servers and consumes much less energy, we are contributing to the timely launch of UHD, large-screen flagship mobile devices,EU said Joo Sun Choi, executive vice president of Memory Sales and Marketing at Samsung Electronics. UHD stands for ultra high definition and could set Samsung apart in a competitive mobile device market.

How Innovative Is It?

The industry is already standing up and taking notice of SamsungEUs latest innovation. The 4GB LPDDR4 package was chosen as an honoree of the 2015 CES Innovation Awards in the Embedded Technologies category. Noteworthy is the fact that Samsung is the only company that has won this particular CES award three straight years with its DRAM solutions.

So, then, what can this new breed of LPDDR do? For starters, the updated model Samsung is mass producing offers twice the performance and density compared to 4Gb LPDDR3. The last generation was also based on 20nm-class process technology but Samsung found a way to drive more efficiencies. The new 8Gb LPDDR4 chip paves the way for the creation of a 4 GB LPDDR4 package.

An I/O date rate of up to 3,200 megabits per second (Mbps) -- a rate thatEUs two times faster than a typical...
