Memory: The ever-predictable DRAM path

PwC forecasts a compound annual growth rate (CAGR) of 48 percent for DRAM (Dynamic Random Access Memory) as measured in Gigabits per dollar (Gb/$) through 2015, compared to a 49 percent CAGR in 2007-2011. While the CAGR as illustrated in the figure above continues a decades-long trend, what is changing is that we have now reached a critical level of performance at which mobile devices can meet and exceed the wide range of uses previously seen only on laptops and desktop computers.

By 2015 average smartphones will have 40 percent of the 4 gigabytes of DRAM that PCs on average have today. Likewise, by 2015 the top 10 percent of smartphones will have 65 percent of the DRAM that PCs have today, and will perform correspondingly. The trend for tablets is even more dramatic.

DRAM is a key enabler of mobile innovation. DRAM and the central processing unit are the heart and soul of any computing device. And today’s mobile devices are powerful computing machines because of the amount of DRAM and powerful processors.

During the five-year forecast period, continued improvement in its CAGR will allow greater amounts of DRAM on mobile devices to support new use cases that involve more data, more computing power and more and different multi-processing.
