Toshiba unveiled its new SmartNAND flash memory on Tuesday with support for flash chips up to 64GB. With a next-generation 24-nanometer process, the new design has a better memory controller that speeds up the read and write process, and is more space efficient – perfect for devices like the iPhone.
It’s possible the new SmartNAND could replace the Samsung flash memory in the current iPhone 4 and allow for a 64GB iPhone 5. Apple has already moved away from the Samsung flash since the launch of the iPhone 4, choosing Toshiba’s NAND flash for both the forth-generation iPod touch and the iPad 2.
The 32GB and 64GB SmartNAND options won’t start being mass produced until at least June, which could be one of the reasons why the launch of the iPhone 5 may be delayed until September – as recent rumors claim.
A 64GB iPhone 4 prototype was recently discovered on the Chinese grey market, and reports at the time ruled out a 64GB forth-generation device, suggesting instead that Apple was testing the larger flash memory for a forthcoming iPhone.
