A more accurate but less inspiring title would be:
RAM Has a Design Tradeoff from 1966. I made another one on top.
The first tradeoff, of 6x fewer transistors for some extra latency, is immensely beneficial. The second, of reducing some of that extra latency for extra copies of static data, is beneficial only to some extremely niche application. Still a very educational video about modern memory architecture.

It could be a display bug on my side, but you posted this exact comment twice.
He tried to reduce latency
This comment was the faster of the two comments and therefor won. The other was simply discarded.
I had to manually delete it.
