Oh, absolutely! There was a lot of work on using

extended what had been done before, and the coincident current
scheme was really ELEGANT and made large arrays of fast memory
practical. The bigger you built the array, the more memory you got
with small increments in the number of drivers.
Didn't coincident-current relays come before that (as used, for example,
in telephone switching equipment)? So the basic idea was there.
I've always been fascinated by magnetic core logic; both using "hard"
magnetics (e.g. Univac SS) and "soft" (e.g. Parametrons). I wonder if
magnetic core for memory hadn't been developed, would we have developed
electrostatic or some other technology to the same density?
Would we have developed ultra-fast recirculating memory?
