The next generation of phones and media tablets could be significantly more powerful than their predecessors and carry up to 4 GB of memory thanks to a new chip from Samsung.
According to a post on Samsung's official blog, the company has developed the industry's first eight-gigabit, low-power Double Data Rate 4 (LPDDR4) mobile DRAM. It plans to use the memory chip in its own products and also license it to third parties.
Enterprise app developers should be prepared to design for devices with higher RAM capacity and the higher-resolution, higher-performance devices that will utilize the new DRAM chip.
"This next-generation LPDDR4 DRAM will contribute significantly to faster growth of the global mobile DRAM market, which will soon comprise the largest share of the entire DRAM market," Young-Hyun Jun, executive VP of memory sales & marketing at Samsung Electronics said in the post.
"We will continue introducing the most advanced mobile DRAM one step ahead of the rest of the industry so that global OEMs can launch innovative mobile devices with exceptional user convenience in the timeliest manner."
DRAM refers to dynamic random-access memory, a form of data storage used in computers and other electronic devices. An increase in DRAM allows a higher level of performance and energy efficiency for applications using mobile memory, which in turn leads to faster speeds for application runtimes, and the capacity for higher-resolution displays without unduly draining battery life.
The 8 GB DRAM chip allows for 1 GB per each silicon die, the highest density currently available. With four of these chips, future classes of mobile devices could have up to 4 GB of RAM. To compare, Apple's iPhone 5s currently offers 1 GB of RAM, while Samsung already offers DRAM chips at 4 GB and 6 GB, allowing device memory of 2 GB and 3 GB accordingly. Samsung's Galaxy Note 3 offers 3 GB of memory.
The possibility of devices sporting higher RAM dovetails with the mobile industry's move towards 64-bit processing. Though Apple was the first to put a 64-bit A7 processor in a smartphone, the iPhone 5s, Qualcomm's announcement of its own 64-bit processor, and Samsung's stated intentions to use 64-bit processors in its next phones imply that the rest of the market is not far behind. Some suspect that Samsung might reveal its new Exynos processors at CES 2014 in January.
In comparison to the previous generation of 32-bit processors, for which 4 GB of RAM is the maximum, 64-bit processors are able, theoretically, to handle up to 16 exabytes of RAM. Future advances in RAM capacity would necessitate an upgrade from a 32-bit architecture to 64-bit architecture.
The 8GB LPDDR4 chip is also more energy-efficient. It enables a data transfer rate per pin of 3,200 megabits per second, twice that of its predecessor, the LPDDR3 DRAM chip, which Samsung claims will allow for 50 percent higher performance while consuming about 40 percent less energy, by way of a new Low Voltage Swing Terminated Logic I/O interface.
According to Samsung, the new 8 GB LPDDR4 DRAM will begin to ship in 2014, and is expected to be used in devices such as high-resolution large screen smartphones, tablets and notebooks as well as high-performance network systems.
