The JEDEC unveiled a new memory interface specifically designed for handheld devices (mobile phone, digital music player, etc.). Its code name LPDDR2:
Low power consumption with a working voltage of 1.2V instead of 1.8V currently.
Able to manage on the same interface and simultaneously flash and DDR2 type of memory.
Energy saving advanced functions allowing to shut down unused chips.
The working frequency of the DDR2 will vary from 100 to 533 MHz.
Overall, it should save 50% of the energy currently spent by the memory part of such handhelds will improving performance. As it is now a JEDEC standard, it should quickly be adopted by manufacturers and invade the future models of devices to be released in the second semester of the year. High-end products will most likely the first target of this new interface, as the saved energy might be recycled to boost other components.
