LPDDR6: Not Just For Mobile Anymore
The new LPDDR6 specification released by JEDEC in July 2025 is expanding beyond mobile devices and making its way into data centers. LPDDR6 offers high capacity and low power consumption, making it suitable for various applications. While HBM is faster but expensive, and GDDR has limited capacity, LPDDR6 strikes a balance between capacity and power efficiency. Frank Ferro from Cadence discusses the suitability of different memory types for various scenarios, including the new security features in LPDDR6 essential for data centers. Working with LPDDR6 presents challenges due to the number of pins and physical layers involved.
