Thin-film memory is a high-speed alternative to magnetic-core memory developed by Sperry Rand in a government-funded research project.
Instead of threading individual

wiring over the alloy dots. This provided very fast access times in the range of 670 nanoseconds, but was very expensive to produce.

line, but general advances in core tended to keep pace.
