IDT Corporation announced the launch of a high-speed multiplexer

     IDT Corporation announced the launch of a high-speed multiplexer that expands IDT's existing DDR4 portfolio for the emerging NVDIMM (non-volatile dual-in-line storage module) ecosystem. In addition, Micron Technology has selected IDT as its preferred supplier of NVDIMM multiplexers for the enterprise and cloud server markets.

     NVDIMM is a new architecture that provides DRAM (dynamic random access memory) data persistence during special events, including catastrophic power outages, by backing up data to non-volatile memory such as flash memory. The multiplexer is a key component of the NVDIMM architecture that isolates the master controller from the DRAM memory during "store" and "recover" operations between DRAM and non-volatile memory.

     Previous multiplexers increase the signal integrity load of the memory channel, which may affect the operating speed. IDT's high-speed multiplexers are specifically designed to mitigate the impact on memory channel signal integrity while enabling DDR4 NVDIMM applications to operate at up to 2,133 Mt /s (megabits per second) and higher bus rates.

     Robert Feurle, vice president of Computing and Network Marketing at Micron Technology, said: "Micron Technology is committed to significantly improving the performance of a wide range of applications and systems by leveraging persistent memory. Our team has been working closely with IDT to develop a new high-speed multiplexer that will be used in Micron's DDR4 NVDIMM products."

     The 12-bit bus switch/multiplexer is in a VFBGA 48-pin package and has a small footprint to replace the data cache on DIMMs in NVDIMM applications. It has a make-before-break circuit to avoid burrs when switching. AC and DC parameters are also optimized for DDR4, ensuring the highest NVDIMMs memory channel performance even when mixed with other types of DIMMs.

     Rami Sethi, vice president and general manager of Memory Interface Products at IDT, commented: "The potential of persistent main memory in servers and storage systems is at a very early stage of realization. As a leading DDR4 NVDIMM component supplier, IDT offers components including NVDIMM carrier clock drivers (RCDS), temperature sensors and now multiplexers, and we have worked hard with leading companies such as Micron Technology. Develop solutions that provide best-in-class performance across both homogeneous and heterogeneous memory channels."
