But with the data center (a building full of computers that runs online services) buildout driving insatiable demand for memory, investors also rewarded startups with alternatives to costly, capacity-limited HBM (memory stacked next to a processor to feed it data faster).

Some are building on commodity DRAM or holding models in on-chip SRAM, while others stack memory directly onto compute. Data movement at all levels of the stack remains a critical bottleneck, too.
