TORONTO -- Just as its predecessors did, the LPDDR4 specification is aiming to double its data rates while slashing power consumption in half, but first publication of the spec by JEDEC won't be until 2014. And even though LPDDR3 is still working to gain traction, most mobile devices (such as smartphones and tablets) are still equipped with LPDDR2.

The LPDDR4 Low Power Memory Device Standard, like its previous incarnations, will be designed to meet the performance and memory density demands of the latest generation of mobile devices, such as smartphones, tablets, ultra-thin notebooks, on the latest, fastest networks.

Hung Vuong, chairman of JEDEC's JC-42.6 Subcommittee for Low Power Memories, tells me the group is finalizing the definition of LPDDR4, and the goal is to publish the specification next year. JEDEC published an update to the LPDDR3 -- first published in the first quarter of 2012 -- in August 2013. The update supports a data rate of 2,133 Mbit/s.
