LPDDR3

LPDDR3, short for Low-Power Double Data Rate 3, is a JEDEC standard for mobile DRAM designed to balance memory bandwidth with low power consumption. It succeeded LPDDR2 and was widely adopted in smartphones, tablets, and other handheld devices where battery life and thermal performance are important. LPDDR3 memory is optimized for reduced operating voltage and enhanced power-management features compared with its predecessor, while delivering higher data throughput.

Technically, LPDDR3 typically operates at voltages around 1.0 to 1.2 volts and supports data transfer rates up to about 1066 MT/s per data line, enabling higher peak bandwidth with lower energy use. The standard uses a multi-bank architecture and includes power-saving modes that help minimize energy consumption during idle periods and in low-activity workloads. These features make LPDDR3 well suited for mobile systems where efficiency is as important as performance.

In device implementation, LPDDR3 memories are commonly deployed in densities that suit mobile platforms and are often assembled in package-on-package configurations alongside application processors, including stacking multiple dies to achieve higher capacities. While LPDDR3 has been largely succeeded by newer generations—LPDDR4 and LPDDR4X in many new designs, followed by LPDDR5—it's still found in older devices and some embedded applications. Major manufacturers such as Samsung, Micron, and SK Hynix produced LPDDR3 memory devices during its peak adoption period.
