I don't think thats true, in embedded architectures its not uncommon to have dual-port RAM.
- phire 6y agoInside chips it's common to have dual port ram. But it's really expensive. I'm not aware of any designs which have large amounts of dual-port RAM as main system memory.
- MrBuddyCasino 6y agoFair enough, I should have been more precise. I wanted to point out that it is not a hard technical limitation, but should have added that in that specific use case it is economically unfeasible.
