Samsung rolls out half‑size LPDDR5X memory packaging for Exynos 2600 processors

Samsung has introduced a new semiconductor packaging method for its upcoming Exynos 2600 smartphone processor. The technique, called Heat Pass Block (HPB), shrinks the LPDDR5X RAM chip to roughly half the size of conventional modules while maintaining full performance. By reducing the chip from 18 to 15 pins and integrating it directly on the 2 nm silicon substrate, the new layout improves space efficiency and thermal management, addressing overheating concerns of high‑performance mobile SoCs.

The HPB approach replaces the older Package‑on‑Package (PoP) design and could become a new industry standard, with analysts noting that Qualcomm’s Snapdragon 8 Elite Gen 6 Pro and other MediaTek chips may adopt similar packaging. Samsung’s advancement signals a shift toward more compact, thermally efficient designs across the flagship smartphone market.
