Marvell has demonstrated a photonic memory module that extends the distance between HBM/DDR and GPUs to 50 meters, breaking the traditional 1.5mm limit. With latency maintained in the hundreds of nanoseconds, this technology decouples compute from memory, allowing AI clusters to scale capacity independently without being constrained by accelerator packaging.
