Intel is strategically positioning itself to leverage the soaring demand for DRAM by collaborating with a SoftBank subsidiary to introduce a groundbreaking memory technology known as “ZAM.”This initiative comes at a time when the proliferation of artificial intelligence (AI) infrastructure has led to unprecedented increases in DRAM requirements, particularly among hyperscalers and semiconductor manufacturers.
Enhanced Power Efficiency with Intel’s ZAM Memory Modules
The global memory supply chain is experiencing significant constraints due to limited availability from current suppliers, highlighting a pressing need for new entrants in the market. In this context, Intel is spearheading a new venture in the memory domain. The firm has entered into a partnership with SoftBank’s Saimemory to formulate a new standard termed Z-Angle Memory (ZAM).
Initial development efforts for ZAM memory technology stem from the Advanced Memory Technology (AMT) program initiated by the U. S.Department of Energy. During this process, Intel presented its state-of-the-art bonding for next-generation DRAM. Although SoftBank’s announcements do not delve deeply into the specific positioning of ZAM memory, insights into Intel’s bonding strategies suggest that ZAM will likely employ a staggered interconnect topology, facilitating diagonal connections across the die stack instead of conventional vertical drilling.
Standard memory architectures cannot meet the needs of artificial intelligence. NGDB defines a completely new approach that will accelerate our move into the next decade.
We are rethinking how DRAM is organized to fundamentally advance computer system architecture, aiming to achieve orders-of-magnitude performance improvements and incorporate innovation into industry standards.

The Z-Angle Memory design intends to utilize a larger section of silicon for memory cells, facilitating increased density while also reducing thermal resistance. This innovative approach may incorporate copper-to-copper hybrid bonding techniques, allowing for more efficient connections between layers and effectively creating a cohesive silicon block rather than discrete stacks. Additionally, ZAM is expected to be a capacitor-less design, integrating Intel’s Embedded Multi-Die Interconnect Bridge (EMIB) for seamless connectivity between the memory and AI processors.
This collaboration between SoftBank and Intel is poised to provide the latter with ownership over the memory stack technology, potentially unveiling advancements with custom Application-Specific Integrated Circuits (ASICs), including the Izanagi series. While exact performance metrics comparing ZAM to High Bandwidth Memory (HBM) remain undeclared, early indications suggest that the Z-Angle design could offer:
- 40-50% Reduction in Power Consumption
- Streamlined Manufacturing via Z-Angle Interconnects
- Enhanced Storage Capacity per Chip (up to 512 GB)
This marks a notable resurgence for Intel in the DRAM sector, as the tech giant previously operated within this market until 1985 when it withdrew due to intensified competition from Japanese firms. Given the current market dynamics and the immense potential in the memory space, it will be interesting to observe how Intel’s ZAM technology evolves and whether it can gain traction among industry leaders, including major players like NVIDIA.
