64Kb note lowercase b, so its an 8kx8 bits, you'd need 8 of them for a
full 64KB. At $11.55 a copy, kind of expen$ive.
Also plenty fast for some video displays at 70 ns access time.

Not right off-hand, but one of them with some support circuitry woulds
sure make a nice COLOR version of a wp-rs. Now thats a tasty thought...
Most of the wp-rs's used a 6116 or a 2028 which was a slower 2kx8 memory
chip, which turned out to be in the one case where I had to replace a
2028, which was a 70 ns chip, with a 6116, a 200ns chip, in something
I've since forgotten what it was used for at the tv station, but that
200ns rated chip, which was cmos, was still working perfectly 10 years
later when I retired, also running relatively cool compared to the nmos
2028's surrounding it.
But whats a F-RAM, terminology I've not encountered closely enough to
remember it. Wet ram and short term memory aren't being as friendly as
