The Triadic Memory, Made Of Core · A Build-On

The Triadic Core

three toroids remember · nine diodes steer · trusted by 2-of-3

The store moved from the diode to the toroid — which is exactly how memory worked for twenty years. Three ferrite cores each hold a bit as the direction of magnetization (CW / CCW remanent flux — non-volatile, no power). Nine diodes, three per core, steer write-in vs read-out and set the circulation. The diodes gate the direction; the toroid remembers. Core memory, recovered — and witnessed by 2-of-3.

The Division Of Labor · gate vs store

the 9 diodes · the gate
A diode is one-way: it steers the write current around the ring (setting which way the core magnetizes) and separates write-in from read-out. But a diode cannot store — a pure-diode array is read-only (that's diode-matrix ROM). The diode picks the direction; it does not hold it.
the 3 toroids · the store
A ferrite toroid holds the bit as the direction of its remanent magnetization (CW=1 / CCW=0), kept by hysteresis with the power off. This is real magnetic-core memory — the dominant RAM ≈1955–1975. The toroid is the persistence the diode lacks.
3 is the minimum store that verifies its own persistence. One core holds a bit but can't witness its own corruption; two can disagree but can't resolve; three triangulate — 2-of-3 outvotes a single flipped core. The Triadic Memory's witness, now over three elements that actually remember.

Why The Read Restores

Sensing a core's direction means flipping it and watching for the induced pulse — so the read destroys what it read. Real core memory always did a read-then-restore cycle: flip to sense, then immediately rewrite. Here, Read flips all three to sense them, takes the 2-of-3 majority, and rewrites that majority back — which also heals any single flipped core in the same stroke.

honest line: "remembers" here means remanent magnetization — non-volatile, the true core-memory mechanism. That's different from a volatile LC circulating current (decays with resistance — a clock, not a stored bit — see the Toroid Tank) and from a superconducting persistent current (remembers indefinitely — MRI / SQUID / flux-qubit). The fault bound is one: with a single bit, three cores always have a majority, so two cores flipped the same way don't read as "no quorum" — they silently flip the trusted answer (flip two and watch). TMR safely masks ONE fault. And the modern one-element answer — a device that both gates AND stores — is the memristor, the diode that remembers.
3 FERRITE TOROIDS (BIT = DIRECTION OF REMANENT MAGNETIZATION, CW=1/CCW=0) · 9 DIODES (3/CORE) STEER WRITE-IN/READ-OUT
DIODE = GATE (ONE-WAY, NO STORE = ROM) · TOROID = STORE (HYSTERESIS = NON-VOLATILE = CORE MEMORY 1955–1975)
READ IS DESTRUCTIVE → SENSE BY FLIPPING → RESTORE THE 2-OF-3 MAJORITY (WHICH HEALS THE LIAR)
