RAM chips of 256 MB for ultra mobiles

Hynix announced to have developed the first chips of 256 MB of DRAM intended for the mobile phones and ultra compact devices.
These chips, contrary to Flash are not intended to be used as permanent memory, but are used as random access memory during operation and allow faster running of the operating system and other processes.
One could imagine that Apple can integrate one of these chips in a forthcoming version of the iPhone. Currently, this has 128 MB of RAM. To double this memory could bring more fluidity, especially with the arrival of increasingly complex applications.
