Emerging technologies such as Internet of Things (IoT), 5G, Automotive, Artificial Intelligence (AI), and High-Performance Computing, have given rise to potentially transformative trends demanding the need for faster memory access. 5G brings with itself the ability for faster download and upload speeds, making high-speed real-time data transfer possible. All the fancy smartphone processors have inbuilt cutting-edge features like high resolution multimedia processing, faster Machine Learning (ML) computations, Image processing capabilities and faster frame rates for all you gaming freaks. But don’t forget underlying all this, is the need for faster memory, AI/ML requires higher bandwidth to support faster processing of massive data.
SoC designs are growing more complex, not just by the sheer number of transistors that can be packed into one design, but the emergence of different interconnect methods you must use to connect chip internals and to connect to the outside world. Becoming an expert on each of the interconnect protocols is not going to shorten the verification schedules, reduce design productivity and expose design bugs that might only be found when used by the end consumer.
JEDEC recently announced the ratification of JESD79-5 DDR5 SDRAM to support the standardization of next-generation memory devices, catering to demand from rapid expansion in high performance computing and data center applications. This new standard promises to deliver 2X memory bandwidth, 4X larger density dies, and much improved power efficiency (1.1V Vdd). The DDR5 DIMM will operate in dual-channel mode all on its own, with two 40-bit fully independent sub-channels on the same module.
Ever-increasing expectations for mobile device performance have been driving the need for versatile mobile memory solutions. JEDEC has recently announced the publication of JESD209-5A which is equipped to match the latest bandwidth, power, performance, and reliability trends. The JESD209-5A standard offers several feature enhancements in addition to the existing LPDDR5 standard, including support for Partial Array Refresh Control (PARC), Refresh Management, Enhanced Write Clock (WCK) Always On Mode, Optimized Refresh, etc. This blog will briefly discuss the new features introduced in the updated LPDDR5 standard which has helped to significantly reduce power consumption and improved in data integrity.

The Joint Electron Device Engineering Council (JEDEC) has been developing and maintaining DRAM standards for years, defining emerging Memory standards like the DRAM standard. The most recent announcement declares the fifth generation of the DRAM, DDR5, is finally ready for release. The work to define DDR5 began in 2017 with the objective of delivering a standard that could move beyond the DDR4 speed limitations of 16 Gb and 3200 MT/s. The intention was to address new applications around data centers high-end servers for handling AI/ML workloads.
We are excited to attend the upcoming JEDEC workshops and tutorial in Santa Clara, October 7th – 10th. The workshops will provide an introduction and in-depth technical review of the DDR5, LPDDR5 and NVDIMM-P standards as well as present the latest reliability and optimization features.
Looking for ways to reduce debug cycles to quickly root cause the issues in your Memory Controller/PHY and Subsystem Verification Project?
Servers are the core of today’s computational world, processing and storing data on multi-user platforms. Server performance depends on latency and capacity of its memory and storage. In general, DDR-DIMMs (Double Data Rate Dual In-line Memory Modules) are used as server memory, whereas SSDs/HDDs are used as storage in server. Whenever a service request is made to the server, it may require both data processing and storage. In order to execute this service, the processor accesses DDR-DIMMs and SSDs/HDDs. In addition, SSDs/HDDs can be accessed in case of power loss, storing data using backup power sources so data can be retrieved once power is available again.
Modern computer applications rely heavily on graphics processing and rendering which involve a lot of simultaneous mathematical calculations. A typical CPU is not suitable for jobs that require simultaneous processing, which is why the concept of a dedicated Graphics Processing Unit (GPU) was introduced. The GPU has found its scope not only in graphics processing but also several emerging applications like AI, machine learning, VR, autonomous driving, and network routing.
LPDDR5: Meeting Power, Performance, Bandwidth, and Reliability Requirements of 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.
