Magnetic-core memory
→
Mercury delay-line memory
replaces
Magnetic-core memory provides random access and retains data without power, gradually replacing delay lines in main memory.
Stored-program computer
→
Mercury delay-line memory
depends on
Early stored-program machines needed main memory that could be read and written repeatedly. Mercury delay lines provided a serial storage solution that was feasible at the time.
