The devices follow a memory standard that was finalized by JEDEC last May and specifically targets connected mobile devices running under 4G networks. While LPDDR3 maintains the power saving features and the signaling interface of LPDDR2, it allows for higher clock speeds, low-power self-refresh, and smart array management.
Samsung's modules are manufactured in 30 nm and run at 1600 MHz, which is 50 percent faster than the preceding memory generation. The maximum data transfer rate is 12.8 GB/s to enable playback of full HD video in real time. Current LPDDR2 modules provide 8.5 GB/s bandwidth.
The introduction of LPDDR3 marks a quick transition from the previous LPDDR2 standard for Samsung. The company began producing its first 2 GB LPDDR2 chips in October of 2011.
First smartphones and tablets integrating LPDDR3 should become available in the second half of next year.
