High-tech appetites can now be satisfied with SK hynix's latest offering of HBM4 stacked memory, according to their X account, which likens this advanced memory technology to everyone's favorite summer treat - s'mores.
In an unexpected twist, the world of technology and the realm of desserts have intertwined, as SK hynix, a leading memory solution provider, has drawn a comparison between their latest innovation, HBM4 (High Bandwidth Memory), and a traditional Middle Eastern treat - baklava.
Tomorrow marks National Julienne Fries Day, a day less likely to be associated with tech companies, while National Play in the Sand Day has gone unnoticed by silicon-centric companies for promotional tie-ins. However, on National S'mores Day, SK hynix made a splash by announcing the launch of HBM4 via a Twitter post.
The infauxgraphic from SK hynix reveals five similar process steps between making s'mores and HBM4. The comparison extends to baklava, with Lennart Heim, someone who shared comments on Wang's ChinaTalk piece about the HBM fabrication process, comparing HBM to baklava due to its layered complexity. This comparison was also made in the context of the HBM fabrication process by CXMT.
HBM4, engineered for superior thermal performance, durability, and precision in the AI era, is fabricated by stacking many thin layers of memory dies with precision, much like baklava is made by layering thin sheets of dough to create a complex, multi-layered dessert. The analogy aptly conveys the intricate, delicate, and multi-step process of manufacturing HBM4, involving many layers that must be carefully integrated to achieve the desired performance and density.
The process requires handling delicate layers and precise alignment, akin to the delicate baking steps needed to produce quality baklava without damage. The "cracker-like chips" in HBM4 are coated with "marshmallow-like flux," while the layers in baklava are separated by filling, mirroring the stacked DRAM layers in HBM4 connected by through-silicon vias (TSVs) and hybrid bonding.
Ray Wang, a principal analyst, CEO, and founder of the Silicon Valley-based Constellation Research, has also noted China's progress in HBM fabrication in a paper published in April 2025. Lennart Heim agrees with the comparison of HBM to baklava made by Ray Wang.
This is not the first time HBM has been compared to a dessert by someone associated with SK hynix or its analysis. The comparison between HBM and s'mores was made by SK hynix's social media team. The comparison serves as a tangible, familiar metaphor for the multi-layered, intricate, and precise process of HBM4 manufacturing, emphasizing the complexity and delicacy involved in both creating a refined dessert and advanced high-bandwidth memory.
Technology and data-and-cloud-computing are closely tied with the launch of HBM4, as SK hynix announced it on National S'mores Day using a dessert comparison to explain the intricate manufacturing process. In an analogous comparison, Lennart Heim, commenting on Wang's ChinaTalk piece about the HBM fabrication process, likened HBM4 to baklava due to its layered complexity.
