Co-designed memory bank
Arithmetic placed deeper beside the memory array than a standard part provides, with compute at every bank, a broadcast input path and a double-buffered command path. This is the mechanism the economics depend on, and the one requiring a memory-industry partner.
Depends on partner co-designNear-bank selection engine
Sparse-attention scoring and top-k selection performed inside the memory device, so deciding which tokens matter does not require moving the tokens.
ModelledContent-addressed sharing
Blocks common to many sessions (a system prompt, a tool schema, a shared document) stored once and referenced by all, with the model's arithmetic performed in place on behalf of every session referencing them.
ModelledIn-path transform and governor
Numeric re-encoding and per-session encryption applied in the same datapath traversal that migrates the session, made idempotent so repeated sleep and wake cycles do not compound error. Our replay established the write governor as mandatory, not optional.
Modelled · governor requiredSustained verification compute
Arithmetic sized for speculative decoding and ingest bursts rather than steady-state decode alone, so the machine does not invert under mixed load.
ModelledIndex-first restoration
A compact per-token index brought up first, scored, and used to gather only what matters while the body of the session stays where it lies. Restoration latency stops scaling with session size.
ModelledWhere the design actually is
Architecture
Defined and maintained under revision control, with a plan of record and a written history of every correction made to it.
Microarchitecture
Specified to block level across the major blocks, with budgets checked mechanically rather than by assertion.
Open
Device timing under confidentiality, durable-tier characteristics, and the co-design engagement itself.
