Looking for a way to reduce effort defining and tracking functional verification goals 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.
We recently published the VIP Newsletter for Apr 2019, containing trending topics, leading solutions, in depth technical articles, videos, webinars, and updates on next generation protocols. In case you missed the latest buzz on Verification IP, you can read it here.
The key features driving future memories are memory density, speed, lower operating voltage, and faster access. DDR5 supports memory density from 8Gb to 64Gb combined with a wide range of data rate from 3200 MT/s to 6400 MT/s. The operating voltage of DDR5 is further reduced from 1.2V of DDR4 to 1.1V.
Synopsys recently announced the fastest, and most power efficient DDR5 and LPDDR5 IP solutions. Industry’s first LPDDR5 controller, PHY, and verification IP solution supports data rates up to 6400 Mbps with up to 40% less area than previous generations. The LPDDR5 IP provides significant area and power savings for mobile and automotive SoCs with its dual-channel memory interface option that shares common circuitry between independent channels. The DesignWare DDR5 IP, operating at up to 4800 Mbps data rates, can interface with multiple DIMMs per channel up to 80 bits wide, delivering the fastest DDR memory interface solution for artificial intelligence (AI) and data center system-on-chips (SoCs). The DDR5 and LPDDR5 controller and PHY seamlessly interoperate via the latest DFI 5.0 interface.
We recently published the VIP Newsletter for Q3 2018, containing trending topics, leading solutions, in depth technical articles, videos, webinars, and updates on next generation protocols.

The growth of datacenter, storage, automotive and other emerging market applications is driving the development of next-generation memory technologies – DDR5, LPDDR5. Like their predecessors, the latest memory technologies also use DFI, a standard interface between memory controller and PHY, to reduce the integration cost and increase performance and data throughput efficiency. DFI also has evolved along with the memory technologies, and next generation DFI 5.0 is here to ensure higher performance in the systems using DDR5/LPDDR5. In this blog, we will discuss the new features of DFI 5.0 specification.
High speed memory interface is a critical component to support high speed data in applications like personal computers, mobile phones, and digital cameras. These applications require a high capacity and high performance NAND flash memory, and Toggle2NAND is one of the most suitable NAND interfaces.
