Montage Technology pioneers CKD DDR5 trial production

CARRY OFF, April 10, 2024 /PRNewswire/ — Montage Technology, a leading data processing and interconnect integrated circuits company, today announced that it has taken the lead in trial production of first-generation DDR5 Clock Driver (CKD) chips for next-generation customer memory. generation. This new product aims to improve the speed and stability of memory data access to match the ever-increasing operating speed and performance of the CPU.

Previously, clock driver functionality was built into register clock driver (RCD) chips used in server RDIMM or LRDIMM modules, not implemented in PCs. In the DDR5 era, as data rates increase to 6400 MT/s and above, the clock controller has become an indispensable component for customer memory.

Montage’s CKD chip is primarily used in DDR5 client memory modules, including CUDIMMs, CSODIMMs, and CAMMs, to buffer clock signals between the client core processor and DRAM, improving the integrity and reliability of the clock signals. high speed clock. The chip meets the JEDEC DDR5CKD01 specification and supports data rates of up to 7200 MT/s. Provides access to double-sided bus addresses and supports I²C and I3C interfaces. By setting register control words, the chip can change the characteristics of its output signal to match various DIMM network topologies. Its power consumption can also be reduced by disabling unused output signals.

“With the continuous development of AI technology, the era of AI-powered PCs is rapidly approaching, driving the demand for DDR5 memory with higher data rate. To further improve the data transfer efficiency of memory, Montage has pioneered the delivery of the first generation DDR5 CKD chip in the industry and successfully achieved volume production,” said Mr. Stephen Tai, President of Montage Technology. “Going forward, Montage will continue to work closely with ecosystem partners to jointly accelerate the development of DDR5 memory.”

Currently, Montage has collaborated closely with the industry’s leading CPU and memory manufacturers, providing bulk shipments of DDR5 CKD chips to memory suppliers. For more details about CKD chips, please click the link:
