Cellphone memory capacity declines as online storage and cloud services increase

Growth in the average amount of NAND flash memory in each smartphone and tablet shipped is slowing this year, as the rising availability of cloud storage and streaming services reduces the need for physical storage in mobile devices, observes the market analysis firm IHS iSuppli.

Memory capacity per cellphone so far has declined to 12.8 gigabytes (GB) on average in the first half of this year, compared to 13.2 GB the same time in 2012, according to a sampling of handsets and tablets studied by the IHS iSuppli Teardown Analysis Service. Such a decline comes in stark contrast to the nearly threefold increase that took place between the first half of 2011 and 2012, when flash memory in phones surged from 4.6 GB to 13.2 GB.

Tablet teardowns tell a similar story of dwindling memory density. From the first half of 2011 to the same time one year later, flash memory loading in tablets dipped 25 percent from 32.1 GB to 24.0 GB on average. The fall during the first half of this year is even greater, down 42 percent as tablet memory skids to 14.0 GB, as shown in the attached figure.

“The increasing prevalence of cloud and streaming services has reduced the requirement for large amounts of NAND flash in smartphones and tablets,” said Ryan Chien, analyst for memory and storage at IHS. “Mobile device brands increasingly are offering their own application ecosystems and online storage benefits that perform the same functions as onboard NAND flash. With mobile platforms a leading growth driver for the NAND industry, this trend represents a major cause of concern for flash memory makers.”

NAND's challenge in smartphones and tablets

The prevalence of smartphones has had the effect of driving up the total amount of NAND flash memory being used in cellphones. However, growth in memory usage overall is flattening. For instance, the most recent iterations of two of the best-selling smartphones in the industry, the Apple iPhone 5 and the Samsung Galaxy S III, have the same storage options as their predecessors. This comes in stark contrast to the past, when a new model from either maker would offer a discernible bump up in NAND flash density
