Memory giant Micron commences delivering HBM4 samples to clients, boasting a 36 GB capacity and a staggering bandwidth of 2 TB/s.
Fired-Up Over Micron's Sizzling HBM4 Memory
Hold onto your data caps, folks, because Micron just cranked up the heat on the memory game with its snazzy HBM4 assemblies! These babies are headed to the next-gen AI and HPC processors, and they're packed with a 36GB punch and a jaw-dropping 2 TB/s bandwidth!
Micron's HBM4 trailblazers are 12-tall memory powerhouses, boasting a staggering 36GB of memory, a 2048-bit wide interface, and data transfer rates hovering around 7.85 GT/s. What's more, these beauty queens are constructed from 24GB DRAM devices manufactured on Micron's 1ß DRAM process tech, along with logic base dies whipped up by TSMC using either their 12FFC+ (2nm-class) or N5 (5nm-class) logic process technology.
As if that ain't enough, Micron's HBM3E memory can top out at 36GB too, but it's a bit of a lightweight compared to its younger sister, boasting just a 1024-bit interface and max transfer rates of 9.2 GT/s (peaking at 1.2 TB/s). But it's no contest; Micron's HBM4 kicks its precursor's butt by offering a whopping 60% higher bandwidth and smoother energy efficiency, a legit 20% improvement! To top it off, Micron's HBM4 even comes with a built-in memory test feature to make integration a breeze for partners.
And no need to worry about Micron having this memory market all to themselves. They'll be the first to dish out HBM4 samples, but Samsung and SK hynix aren't far behind. Volume production of HBM4 is slated to begin in 2026, around the same time leading AI processor manufacturers start churning out their next-gen hardware.
It's predicted that Nvidia's Vera Rubin datacenter GPUs will be the first to get cozy with HBM4 later in 2026. Count on other AI and HPC processors to hop aboard this HBM4 hype train soon enough.
"Micron's HBM4 memory is the real deal," says Raj Narasimhan, senior vice president and general manager of Micron's Cloud Memory Business Unit. "We're crushing it with our memory technology and product leadership, and we're just getting started. Our innovation with HBM4 and our killer AI memory and storage solutions are going to take the tech world by storm. The HBM4 production milestones line up perfectly with our customers' next-gen AI platform readiness for seamless integration and mass production."
