CES 2020: Micron begins to provide DDR5 memory samples to server partners

Micron announced at the Consumer Electronics Show (CES 2020) that it has begun to provide DDR5 RDIMM memory samples to specific partners, meaning that the latter already has a server CPU/platform that supports DDR5 memory. The company expects its first-generation DDR5 products to deliver 1.85 times more performance improvements than JEDEC-standard DDR4 memory. In addition to data transfer rates up to 6400 MT/s, two separate 32/40-bit channels (supported/not supported with ECC checking) are used for each DDR5 module, increasing channel utilization.

In addition, DDR5 improves the efficiency of the command bus because these channels have their own 7-bit address (Add)/command (Cmd) bus, a better refresh scheme, and an additional Bank Group addition.

More importantly, the DDR5 specification allows the design of memory particles with a capacity of more than 16Gb, reduces the operating voltage to 1.1 V, and allows a range of 3% (?0.033 V).

In other words, next-generation memory reduces power consumption and is used to build servers with higher storage capacity. Increased memory bandwidth and capacity are critical for next-generation server platforms that use more processor cores.

Although Micron has not disclosed the exact sample specifications for DDR5 RDIMM memory provided to partners or will begin commercial sales, we can speculate that dDR5-enabled servers will be available in a few quarters and the platform developers are already setting a launch date.

“Data center workloads are increasingly challenging,” said Tom Eby, senior vice president and general manager of Micron’s computing and networking business.

To derive value from the explosive growth of data across all aspects of business and individuals, you need faster, more storage-dense memory.

Micron’s DDR5 RDIMM sample represents a milestone for the server platform as it takes an important step in leveraging the scalability of next-generation memory.
