High Bandwidth Memory (HBM) is the commonly used type of DRAM for data center GPUs like NVIDIA's H200 and AMD's MI325X. High Bandwidth Flash (HBF) is a stack of flash chips with an HBM interface.

The HBM1 stack had four dies and two 128-bit channels per die or 1,024 bits, and putting four stacks on a device yielded 16 GB of total memory and 4,096 bits of memory width, which is eight times that ...

Memory innovation for AI is accelerating rapidly, but power demands are skyrocketing, raising serious sustainability and ...

The problem is when one memory stack grows too much and gets too close to another program's stack. In 2005, 2010, and again in 2017, researchers have found a way to confuse the operating system ...

By using the 1β process node, Micron says that its second-generation HBM3 stack delivers 2.5x more performance for the same amount of power as an HBM2 stack with 50 percent faster data-transfer ...

Kernel-mode Hardware-enforced Stack Protection is a security feature introduced in Windows 11 22H2 that protects systems from various memory attacks, such as stack buffer overflows.

In brief: GPUs have memory limitations when facing the demands of AI and HPC applications. There are ways around this bottleneck, but the solutions can be expensive and cumbersome. Now, a startup ...

There’s memory, and there’s ways to use it. I was the sysadmin for an IBM AS400 in the 80s and 90s. Refrigerator-sized beige box, CISC technology (before the great migration to RISC and POWER ...
