An Active edge connector for memory modules has a base including two PCB sides and a spacer separating the sides, with driver chips mounted on each side of each side, printed wiring electrically connecting a first set of electrical signals from each of the driver chips to a mother board on which the connector is mounted, and printed wiring for electrically connecting a second set of electrical signals from each of the driver chips to a memory module inserted in the edge connector. When a group of connectors are mounted on a mother board, electrical signals arriving at the first connector are routed to its driver chips, producing re-driven signals to the next connector, and so on. A decoder circuit provides addressing signals determining the last such connector to which the signals are intended, and which prevents the signals from going to any connectors containing memories not addressed.
