Synopsys Announces Fastest, Most Power Efficient DDR5 and LPDDR5 IP Solutions

New Designware Memory Interface IP Targets AI, Automotive, and Mobile SoCs

Synopsys, Inc. (Nasdaq: SNPS) announced new DesignWare Memory Interface IP solutions supporting the next-generation DDR5 and LPDDR5 SDRAMs. The DDR5 and LPDDR5 IP significantly increase memory interface bandwidth compared to DDR4 and LPDDR4 SDRAM interfaces, while reducing area and improving power efficiency. 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 industry’s first LPDDR5 IP, running at up to 6400 Mbps, 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. For additional power savings, the DesignWare Memory Interface IP solutions provide several low-power states with short exit latencies, and offer multiple pre-trained states for dynamic frequency change capability. The DDR5 and LPDDR5 controller and PHY seamlessly interoperate via the latest DFI 5.0 interface, providing a complete memory interface IP solution for high-bandwidth, low-power SoC designs.
