Cadence has announced what it calls the industry’s first LPDDR5X 9,600 Mbps memory IP system solution designed specifically for enterprise and data center applications requiring high reliability. The offering integrates Cadence’s production-proven LPDDR5X IP with Microsoft’s redundant array of independent double data rate (RAIDDR) error correction code (ECC) coding schema, targeting higher reliability while maintaining low-power operation. Cadence says Microsoft is the first customer to deploy the system solution.
Cadence positions the release around AI infrastructure where low-power double data rate 5X (LPDDR5X) is gaining traction in data centers for energy efficiency and performance across AI, high-performance computing (HPC), and other memory-intensive workloads. The company says hyperscalers have faced a tradeoff between power, performance, and area (PPA) and the reliability, availability, and serviceability (RAS) commonly associated with double data rate 5 (DDR5) memory; Cadence says this LPDDR5X-based approach aims to deliver enterprise RAS capabilities while maintaining PPA in a compact form factor.
Cadence says the solution supports up to 9,600 Mbps data rates and provides sideband ECC performance comparable to traditional DDR5 ECC implementations for data center use. It also states that Microsoft’s RAIDDR ECC coding schema is designed to achieve “close to single device data correction (SDDC),” with “industry-leading accuracy and fault detection with minimal logic overhead,” and that RAIDDR provides protection equivalent to symbol-based ECC typically associated with DDR5 registered dual in-line memory module (RDIMM) applications.
Cadence lists the following technical characteristics: support for 40-bit channels using LPDDR5X dynamic random-access memory (DRAM); 9,600 Mbps performance combined with low power consumption; enterprise-grade RAS with DDR5-style symbol-based ECC reliability; sideband ECC support for maximum channel bandwidth; and a compact form factor intended for space-constrained systems.
“Our LPDDR5X 9600Mbps system solution marks a major milestone in memory innovation for the enterprise and data center markets,” said Boyd Phelps, Senior Vice President and General Manager of the Silicon Solutions Group at Cadence. “By combining the speed and power efficiency of LPDDR5X with the reliability of Microsoft’s innovative RAIDDR ECC technology, we’re delivering a solution that redefines what’s possible in high-performance, low-power memory systems.”
