Persistent State Machines: LLM Attention with INT4 In-Memory Cells

Share

If INT4 in-memory cells can reliably approximate attention, the constraint on scaling shifts from FLOPs to memory architecture. For teams pushing context length or on-device models, this is a nudge to track memory-centric designs, not just new GPU SKUs.

Startup swaps costly AI GPUs for Arm cores and up to 128TB of 'cheap' LPDDR6 RAM instead of expensive HBM to smash through the memory wall

If Majestic Labs can make Arm + 128TB LPDDR6 viable for inference, the constraint shifts from flops to memory bandwidth and data locality—good enough compute with huge cheap memory is a different design space than GPU + HBM. For operators, this is an early signal to segment workloads by memory footprint and tolerance for latency rather than defaulting everything to GPU clusters.
