Going back to a thread from a week or two ago, and just for the sake
of providing a datapoint, while looking for some other IC data in a
Motorola 1969 Semiconductor Databook, I noticed:
MC1170L PMOS 64-bit RAM
- organised as 16 words of 4 bits
- binary addressable (4 address lines, 4-bidir data lines)
Also ran across mention of:
"Intel's first commercial chip, the 3101, a 64-bit static RAM
using Schottky TTL"
dated at 1969, at:

(Nice page if one is interested in early IC developments.)
This display terminal was designed in 1969,
[...] Remember,
in that time, there are no micro-processor, neither RAM chips!
There were RAM chips in 1969. Most of them stored 16 bits or
less. I have not been able to determine when the first 64-bit RAM
appeared, but it might have occurred by then.
