Circuit neuralizer

A circuit neuralizer is a special pre-War tool designed to modify artificial memory storage units, like the ones used in Institute androids. It allows a capable technician to reroute signals in the memory, up to and including creating them from scratch.

Although the device is complex, gifted engineers are perfectly capable of reconstructing them given the appropriate diagrams are available. Horace Pinkerton is known to have constructed one using spare parts and information salvaged from Vault 112.
