LPDDR3 standard for low power memory devices published by JEDEC

JEDEC Solid State Technology Association has announced the publication of JESD209-3 LPDDR3 low power memory device standard, designed to satisfy the performance and memory density demands of the latest generation of mobile devices such as smartphones, tablets, ultra-thin notebooks and similar connected devices on the newest, high-speed 4G networks. LPDDR3 offers a higher data rate, improved bandwidth and power efficiency, and higher memory densities.

Developed by JEDEC's JC-42.6 subcommittee, the LPDDR3 standard is available for free download from the JEDEC website: http://www.jedec.org/standards-documents/results/jesd209-3

LPDDR3 achieves a data rate of 1600Mbps (versus 1066Mbps for LPDDR2) through the addition of new features, including:

1. Write-leveling and CA training: These features allow the memory controller to compensate for signal skew, ensuring that data input setup and hold timing as well as command and address input timing requirements are met while operating at input bus speeds.
2. On Die termination (ODT): This optional feature enables a light termination to LPDDR3 data lanes to improve high-speed signaling with minimal impact on power consumption, system operation and pin count

The LPDDR3 supports both package on package and discrete packaging types in order to meet the requirements of a wide array of mobile devices.

"LPDDR3 builds on the revolutionary LPDDR2 standard, which paved the way for an entire generation of high-performance, low-power mobile devices," said Mian Quddus, JEDEC board of directors chairman. "Now with LPDDR3, JEDEC has taken the standard to a new level, and we are pleased to offer a solution for the performance demands of a new generation of mobile products."

"To help address the dramatic rise in data-intensive apps and the resulting demands on device memory, JEDEC LPDDR3 is designed to focus on higher bandwidth requirements for device processors and graphic units," added Hung Vuong, chairman of JC-42.6. "LPDDR3 represents countless hours of collaboration within the JC-42.6 Subcommittee, and was developed rapidly in order to meet the mobile industry's bandwidth requirements."
