XCENA raises $135M on a bet that AI's real bottleneck is memory, not compute
XCENA, a chip startup founded by Samsung and SK Hynix veterans, secured $135 million in Series B funding at a $570 million valuation. The company's MX1 chip addresses the AI memory bottleneck by placing compute capabilities directly near DRAM, eliminating costly data round trips between CPUs, GPUs, and memory that slow down AI inference and drive up infrastructure costs.
