Rambus has announced the availability of its fourth-generation RCD (Register Clock Driver) chip for DDR5 memory, as reported by Wccftech. The RCD chip plays a crucial role in products like RDIMMs, caching signals such as addresses, commands, and control from memory controllers, essential for server-grade memory modules.

Features of the RCD Chip

The DDR5 fourth-generation RCD chip from Rambus supports a clock frequency of 3600MHz and an effective rate of 7200MT/s. In practical terms, this translates to a memory bandwidth 1.5 times that of the first-generation DDR5-4800, meeting the demands of AI generation and other advanced data center workloads more effectively.

Additionally, the RCD chip operates at a standard VDD voltage of 1.1V, ensuring lower power consumption. It also features an I3C bus interface with speeds up to 5MHz.

Statement from Sean Fan, COO of Rambus

Sean Fan, Chief Operating Officer at Rambus, emphasized the critical role of memory in driving server performance. He highlighted that the advancements in DDR5 technology, particularly with the fourth-generation RCD chip, are poised to enhance efficiency and performance in data-intensive applications.

Conclusion

With the introduction of its DDR5 fourth-generation RCD chip, Rambus continues to innovate in memory technology, addressing the increasing demands of high-performance computing environments.
