Josephson–CMOS Hybrid Memory Lab

SFQ control speaks pulses; CMOS array speaks levels. Embassy = megaphone (SQUID stack / 4JL) outbound + return interface. Density in the warehouse; speed in the pit crew.

Hybrid does not erase encoding differences — it manages them at a boundary. VT-RAM keeps bits in flux; this warehouse keeps them as CMOS levels.
