"With tablets handling more data-intensive applications such as video, the average DRAM content in these platforms during 2011 will be about two-and-a-half times more than last year's 274MB," said Mike Howard, principal analyst for DRAM & memory at IHS. "The rapid expansion will continue next year, when average DRAM in tablets reaches approximately 1.3GB. In 2015, tablets will have DRAM content similar to that of today's laptops, reaching 3.7GB."
Tablet DRAM density will expand at a CAGR of 68% from 2010 to 2015.
Despite the substantial increase this year of DRAM content in tablets, growth could have been even greater if Apple's recently-released iPad 2 turned out to have the full 1GB of DRAM - similar to the iPad's competitors, which prior assumptions seemed to indicate - instead of just 512MB, IHS said. In comparison, the Xoom by Motorola, the TouchPad by Hewlett-Packard (HP) and the BlackBerry Playbook by Research In Motion (RIM) - tablet devices competing with the iPad - each has 1GB of DRAM.
Apple's choice to include only 512MB of DRAM is not really surprising, however, given that the company is attempting to focus on the overall tablet experience rather than its product specifications, IHS believes. Just the same, Apple's dominance of the tablet market at present - taken in consideration with the 512MB in its iPad devices - means that the overall increase in DRAM content this year was much less than if Apple had used 1GB.
Meanwhile, speculation abounds that the next version of the iPad might feature a Retina display similar to Apple's iPhone 4 and iPod Touch. If this turns out to be true, DRAM content surely will jump to 1GB, Howard predicts, which then would alter the forecast and result in even greater DRAM content growth in tablet devices. Future releases of the iOS operating system by Apple might also unleash iPad functionality that could require more DRAM.
DRAM growth in tablets is mirrored by a similar increase of DRAM content this year in smartphones, projected to grow 62%; and in tablets, expected to climb 33%, according to IHS. Around the 2012 to 2013 time frame, tablets will become a significant DRAM category rivaling smartphones. And while both tablets and smartphones use less DRAM content per device than PCs, their combined shipments in 2011 will outnumber those of PCs, making them categories well worth watching in the DRAM arena.
