Smartphones moving to fancier flash drives
 

Memory chip makers will offer more sophisticated flash drives for smartphones--technology that will be comparable to the solid-state drives found in laptops today.

Today's flash drives, which typically range up to 32GB in capacity in products like Apple's iPhone, often use relatively unsophisticated techniques for reading and writing data. In general, the technology is not very different from that used in basic cell phones or digital cameras, according to Brian Shirley, vice president of Micron's memory group.

But as smartphones--and possible future tablet devices--become more like personal computing devices and less like basic MP3 players, memory chip makers will begin offering more sophisticated flash memory, said Shirley, in a phone interview.

"In nearly all MP3 players today it's almost exclusively 'raw' NAND. And at some point we anticipate moving more to a managed NAND," Shirley said. NAND is the type of flash memory chip used in all flash cards and solid-state drives.

Managed NAND falls somewhere between very basic flash drives--such as Secure Digital, or SD, cards--and pricey solid-state drives (SSDs) used in laptops and servers. "It's something in between the raw NAND that we've been talking about for cell phones and MP3 players and the full-blown SSD space," Shirley said.

"We believe this will be fairly busy (market) space in 2010," he added.
