Data Centers Drive DDR5 Demand
By Gary Hilson 01.31.2020

Server segments are driving significantly higher performance requirements from memory subsystems.

TORONTO — Micron Technology chose CES 2020 to unveil its DDR5 chip, which is ironic, since the latest iteration of DRAM will initially find the most demand from data center applications before popping up in client devices.

In amongst giant wall-mounted LEDs, smartphones, and “impossible pork,” Micron announced it had begun sampling its DDR5 Registered DIMMs based on its industry-leading 1znm process technology. Director of data center marketing Ryan Baxter told EE Times in a recent telephone interview that because DDR5 doubles memory density, it will feed the need in data centers for growing processor core counts with increased memory bandwidth and capacity. However, it will be nine months to a year before sampling will begin in large quantities to a wide variety of customers, he said.

“Mainstream customer sampling begins the latter part of 2020, in preparation for a ramp that’s going to occur right around about a year from now,” Baxter said.

DDR5 adoption is expected to be driven primarily by the enterprise and cloud space server segments, according to Baxter. “The next generation CPUs are going to need a whole lot more memory performance to be able to be optimized for what the customers are typically using CPUs for these days.”

Client adoption will follow, he said, but how a new DRAM spec gets traction has changed in the last three or four years when clients such as PCs were a massive part of the overall DRAM demand envelope. “They’re still big, but cloud and enterprise essentially have surpassed clients in terms of the size of the demand for DRAM these days.”
