JEDEC releases new SPHBM4 standard to slash AI memory costs — Narrow 512-bit interface enables dropping expensive interposers for organic substrates
SPHBM4 promises HBM4-class bandwidth without usage of silicon interposer and CoWoS-like packaging.
The increasing demand for AI memory is driving innovation in packaging and interface standards to reduce costs and improve efficiency, making new standards like SPHBM4 timely.
This new standard offers a pathway to significantly reduce the cost and complexity of high-bandwidth memory for AI, potentially accelerating wider AI adoption and innovation.
The ability to achieve HBM4-class bandwidth without expensive interposers and CoWoS-like packaging will make advanced memory more accessible and less costly to integrate.
