64GB iPhone and 128GB iPod Touch Possible in 1st Quarter 2010?
Toshiba announced (via 9to5Mac) that they have launched a 64 gigabyte (GB) embedded NAND flash memory module. The new chip offers 64GB on a single chip and will start mass production in the first quarter of 2010.
The reason the largest iPhone (32GB) currently has 1/2 the memory of the largest iPod touch (64GB) is that the iPhone can only house a single NAND flash chip while the iPod touch can accommodate two. The additional space in the iPhone is taken up by its communication hardware. This new advancement should allow for 64GB iPhones and 128GB iPod touches in 2010.
Last year, Toshiba first announced their 32GB NAND flash modules which apparently ended up being used in the latest iPhone revision. iSuppli's teardown identified Toshiba as the supplier of the iPhone 3GS's flash memory.
