Micron Samples 128 GB Modules Based mostly on 32 Gb DDR5 ICs

Micron is sampling 128 GB DDR5 reminiscence modules primarily based on monolithic dies, the corporate said at its earnings name this week. The modules are primarily based on monolithic 32 Gb DDR5 memory devices that the corporate introduced earlier this summer season and which is able to finally open doorways for 1 TB reminiscence modules for servers.

“We expanded our high-capacity D5 DRAM module portfolio with a monolithic die-based 128 GB module, and we’ve began transport samples to prospects to assist assist their AI software wants,” stated Sanjay Mehrotra, president and chief government of Micron. “We count on income from this product in Q2 of calendar 2024.”

Micron’s monolithic 32 Gb DDR5 dies are made on the corporate’s 1β (1-beta) manufacturing course of, which is the final manufacturing node that solely depends on multi-patterning utilizing deep ultraviolet (DUV) lithography and doesn’t use excessive ultraviolet (EUV) lithography instruments. That is all that we find out about Micron’s 32 Gb DDR5 ICs at this level, although: the corporate doesn’t disclose its most pace bin, although we will count on a drop in energy consumption in comparison with two 16 Gb DDR5 ICs working on the identical voltage and information switch fee.

Micron’s new 32 Gb reminiscence chips pave the way in which for creating a normal 32 GB module for private computer systems with simply eight particular person reminiscence chips and a server-oriented 128 GB module primarily based on 32 of such ICs. Furthermore, these chips make producing reminiscence modules with a 1 TB capability possible, deemed unattainable right this moment. These 1 TB modules may appear extreme for now, however they profit fields like synthetic intelligence, Massive Information, and server databases. Such modules can allow servers to assist as much as 12 TB of DDR5 reminiscence per socket (within the case of a 12-channel reminiscence subsystem).

Talking of DDR5 reminiscence typically, it’s noteworthy that the corporate expects that its bit manufacturing of DDR5 will exceed that of DDR4 in early 2024, putting it a bit forward of the business.

“Micron additionally has a powerful place within the business transition to D5,” stated Mehrotra. “We count on Micron D5 quantity to cross over D4 in early calendar 2024, forward of the business.”
