New market map: compute-in-memory chips in 2026 — 88 companies, 13 layers
The biggest valuations aren't in true in-memory compute. Unconventional AI (analog, route undisclosed) is at $4.5B and d-Matrix (digital in-memory, data-center inference) at $2B, while Cerebras, the big-SRAM neighbor, sits at $56.4B.
Layer by layer:
1. RRAM / memristor (8) — Mentium, Innostar (ReRAM pilot line), MemSilicon (RMB 400M+ raised). Weights stored as device conductance.
2. Flash / NOR (4) — Mythic ($125M raised), Witmem, UCUN, Anaflash. Mature flash cells doing analog multiply-accumulate.
3. Charge-domain & other analog (10) — Unconventional AI ($4.5B val.), EnCharge AI ($100M+ raised), Sagence (~$58M), Aspinity, Blumind.
4. Digital CIM at the edge (9) — Axelera AI ($250M+ raised), Houmo (160 TOPS), GSI Technology ($25.1M revenue), PIMCHIP.
5. Digital CIM for the data center (6) — d-Matrix ($2B val.), Fractile ($220M), Rain AI. In-memory plus chiplets for LLM inference.
6. DRAM / HBM near-memory (10) — XCENA ($570M val.), NeuroBlade ($83M), Samsung HBM-PIM (1.2 TFLOPS), SK hynix AiM, UPMEM.
7. Edge at-memory (3) — MemryX ($44M raised), Syntiant ($271.8M revenue in 2025), Untether AI (team joined AMD).
8. Big-SRAM chips (4) — Cerebras ($56.4B), SambaNova ($11B), Groq ($3.5B), Graphcore. Trade on-chip SRAM for bandwidth; not true in-memory.
9. Research lines (11) — imec (2,900 TOPS/W), TSMC (254 TOPS/W, 5nm digital macro), Intel 18A (147 TOPS/W), IBM NorthPole, Stanford NeuRRAM.
10. Photonic computing (7) — Lightmatter ($4.4B val.), Celestial AI ($2.5B), Neurophos ($110M), Q.ANT. Light for matrix math and interconnect.
11. Neuromorphic (7) — Intel Loihi / Hala Point (1.15B neurons), BrainChip, Innatera, SynSense.
12. Memory IP & devices (8) — Weebit Nano, Everspin ($20.6M quarterly revenue), Ferroelectric Memory Co (EUR 100M).
13. Equipment, materials & EDA (1) — Applied Materials.
