Pat Gelsinger's Playground backs Nagare Labs with $5M to break AI's memory wall
What's the deal? Nagare Labs, a Georgia Tech spinout, emerged from stealth with a $5 million seed round led by Playground GlobalDealroom has a profile for this one. Try Dealroom →. The Atlanta startup is building Z2RAM, a new memory architecture designed to combine the speed of SRAM with the density of DRAM.
Who's behind it? Nagare was co-founded by Dr Suman Datta and Dr Shimeng Yu, both Georgia Tech professors. Datta co-invented Intel's High-k/Metal Gate and Tri-gate transistor architectures; Yu created NeuroSim, an open-source simulator used widely to model emerging memory.
Why now? AI compute has outrun memory. Peak compute performance has grown 70% annually over three decades, while memory bandwidth has climbed just 20% — a gap that throttles generative AI inference workloads.
What's the endgame? Z2RAM is a capacitor-less, transistor-based design that layers memory directly on top of a logic die, cutting the energy and latency cost of moving data off-chip. Nagare says it uses standard fabrication processes and materials rather than exotic ones, which it argues makes it easier to commercialise.
What did backers say? "Unlocking the full potential of next-generation AI requires fundamentally rethinking hardware from the memory layer up," said Pat Gelsinger, general partner at Playground Global and former Intel chief executive officer. Nagare's design "operates on existing fab infrastructure," he added.
What could go wrong? Nagare is still at the lab-prototype stage and seeking a fabrication partner. Its claims about speed and density are company targets, not independently demonstrated results, and its own roadmap puts samples years away and production further out.
The signal: The round is an early bet on a costly bottleneck rather than a near-term fix. With high bandwidth memory supply expected to stay tight into 2027 and established suppliers expanding capacity, the incentive to find alternatives is real — but so is the bar for a new entrant.
