launched a new 64GB flash memory module that is designed for use in portable
devices. The company claims the new module is the highest-capacity flash module
in the industry. The new 64GB NAND flash module is 30 micrometers thin and has
a dedicated controller and sixteen 32Gbit chips. It is manufactured using
Toshiba's 32-nanometer process technology.
Toshiba currently supplies the flash memory for Apple's iPhone
3GS, so this announcement
has led many to speculate that future generations of the iPhone will use the
higher capacity 64GB module. The new modules are set to arrive early next year.
Recent rumors have suggested that the fourth-generation iPhone will arrive
sometime next summer, though neither Apple nor Toshiba will confirm this.

If the 64GB module is used in an iPhone-like device, it
would provide enough storage capacity for 1,000 hours of music, 8 hours of HD
video, and 19 hours of SD video. Toshiba plans to ship samples of the 64GB
memory module later this month with mass production beginning in the first
quarter of 2010.
