EL SEGUNDO – Shipments of dynamic random access memory for use in smartphones are set for triple-digit growth this year, outpacing the expansion of the entire DRAM market by a factor of three, according to IHS iSuppli.

DRAM shipments in smartphone handsets, as measured in 1 Gb-equivalent units, are expected to rise to 1.7 billion in 2011, up 157.2% from 2010. By 2015, shipments will increase to 13.9 billion units, up 700% from 2011.

Smartphones’ share of total DRAM consumption will grow to 7.6% this year, up from 4.4% in 2010, says IHS iSuppli. This will expand to 10.6% next year and then climb to 13.4% in 2013, 14.9% in 2014 and 16% in 2015.

In at least four recently released smartphones, dissections by IHS iSuppli revealed the devices had larger quantities of DRAM.

The Xperia PLAY from Sony Ericsson, for instance, had 512MB of DRAM, while the Galaxy Indulge from Samsung featured 576MB. The iPhone 4 from Apple had DRAM amounting to 544MB, while the Thunderbolt from HTC had the highest level at 768MB.

In comparison, a device released last year, such as the SGH T939 – an Android-operated, touch-screen smartphone from Samsung – had DRAM content of only 128MB, says the research firm.

Projections call for the average smartphone DRAM density to reach 715MB next year, up 55% from 461MB in 2011, with no near-term limitations on growth.
