AI inference keeps getting pricier, and a lot of that cost is memory. High Bandwidth Flash (HBF) aims to change that: HBM-class speed, up to ~16x the capacity, far less per GB. What it is, how it could cut inference cost, and why it isn't shipping yet.

If you run AI models in production, you've probably noticed how much of the cost traces back to memory.
Every token a model generates is served from fast memory sitting right next to the GPU. That memory — High Bandwidth Memory, or HBM — is scarce, expensive, and effectively sold out for 2026. It's the same crunch that pushed DDR5 prices several times higher this past year. For long-context models and agents, memory is now the single largest cost driver in inference.
High Bandwidth Flash (HBF) is built to attack that. The idea: take the cheap, dense flash from SSDs and rebuild it to keep pace with a GPU — much of HBM's bandwidth, up to 8–16x the capacity, at a fraction of the cost per GB. In one vendor simulation, an HBM+HBF hybrid hit up to 2.69x higher throughput per watt than HBM alone.
The catch: HBF isn't shipping. Samples are due in late 2026, first systems in 2027 — the savings so far live in simulations, not invoices.
New explainer covers what HBF is, how it would cut cost, the alternatives (CXL, processing-in-memory, LPDDR modules), and how seriously to take the claim.

Oh, Sally McKee, the sage of "the Memory Wall," has finally met the ultimate blue screen of death 💻🔪. A computer science guru who probably left her own memory wall after forgetting to install the latest life updates, she’s now rebooting in the cloud. May the RAM be with her. 🙄💾

Taalas just emerged from stealth with a claim that’s shaking the hardware world: 17,000 tokens per second on Llama 3.1 8B.
How? By physically etching the AI model directly into the silicon transistors. No HBM. No liquid cooling. Just raw, hardwired performance that is 10x faster and 20x cheaper than traditional GPU inference.

Memory wall: что это и почему важно для индустрии хранения данных
Серверы становятся мощнее и больше каждый год. Количество ядер растет, векторные блоки для параллельной обработки массивов данных одной инструкцией расширяются, частоты давно уперлись в физические ограничения. Но вычислительная плотность продолжает увеличиваться. При этом производительность памяти и систем хранения растет существенно медленнее. В результате в реальных системах процессор все чаще простаивает, так как технически готов выполнять инструкции, но вынужден ждать, пока данные будут доставлены из хранилища. Это явление давно известно в архитектуре вычислительных систем как разрыв между процессором и памятью (или Memory Wall). Сегодня он определяет производительность серверов, баз данных, платформ данных и AI/ML-платформ сильнее, чем выбор конкретной модели процессора или видеокарты. А в будущем определит то, какие продукты и решения индустрия будет использовать для решения задачи хранения данных. Привет! Я Александр Гришин, руководитель по развитию продуктов хранения данных
