R+ LPDDR3 DRAM

Bringing next-generation, low-power performance to the market today, our R+ LPDDR3 DRAM improves power consumption and performance in smartphones and tablets while maintaining compatibility with existing LPDDR3 and LPDDR3e specifications. When paired with the R+ LPDDR3 PHY, the DRAM supports data rates of up to 2133 Mbps, while providing an active power reduction of up to 30% when compared to a standards-only LPDDR3 device at the same speed.

How it works

Today’s smartphones and tablets demand longer battery life combined with increased memory bandwidth to support popular high-performance applications such as HD video capture and content streaming. The R+ LPDDR3 DRAM delivers the level performance and power efficiency combined with the standard compatibility required for mobile device makers to meet and exceed growing consumer expectations.

Compatible with LPDDR3, LPDDR3e and enhanced R+ LPDDR3, our R+ LPDDR3 DRAM supports data rates up to 2133 Mbps at up to 30% lower DRAM active power (IDD4R) versus standard LPDDR3 when paired with our R+ LPDDR3 PHY. The improvement in power consumption is due in part to the use of Low Voltage Swing Terminated Logic (LVSTL) signaling technology, which features a significantly reduced signal swing versus the 1.2 volt HSUL (High Speed Unterminated Logic) signal swing of LPDDR3. By supporting both signaling types, the R+ LPDDR3 DRAM offers an enhanced performance, low-power mode while maintaining compliance with LPDDR3e and LPDDR3 standards and specifications.
