The mobile industry is growing at a very fast pace with its never-ending hunger for data and bandwidth. We have witnessed the change from a dial-pad to touch-screens, from black and white display to QHD 4k display with millions of colors, and memory space from KB to GB, in a very short span of time. The biggest challenge is increasing bandwidth without compromising performance or adding any significant numbers in the power consumption column. The solution to this challenge are the LPDDR or Mobile DDR standards released by JEDEC. There have been several revisions to this standard, the latest being LPDDR4. LPDDR4 provides a data bandwidth of 4266 Mbps, which is almost double that of LPDDR3. It also provides a significant reduction in power consumption compared to LPDDR3. For further insights on LPDDR4 and its predecessors please refer to our previous blog “LPDDR4: What Makes it Faster and Reduces Power Consumption.”

In this blog, we will discuss the features which make LPDDR4 efficient in terms of power consumption, bandwidth utilization, data integrity and performance.
