LPDDR5 new features for AI, IoT, and automotive

The semiconductor industry is buzzing with new technologies – Artificial Intelligence (AI), Machine Learning (ML), IoT, Automotive, etc. – bringing a revolution by easing out our day-to-day lives and improving considerably performance, bandwidth and reliable data processing and transfer. Reliability and data integrity are even more important for safety critical verticals where even the slightest error can be catastrophic. Stepping up to meet industry trends, JEDEC recently announced its fifth revision of LPDDR standard JESD209-5 which is all equipped to match the latest bandwidth, power, performance, and reliability trends. Immediately following this, Synopsys announced the Industry’s First LPDDR5 IP & VIP Solution Extending Leadership in DDR5/LPDDR5. Strengthening our leadership in memory VIP, recently we also announced the Industry’s First DDR5 NVDIMM-P Verification IP, showing our continued collaboration with leading memory vendors.

LPDDR5 supports a data bandwidth of 6400Mbps with a voltage swing as low as 0.3V. This blog will briefly define the new features introduced in LPDDR5, starting with the features that help to significantly reduce power consumption.
