It doesn’t mean that RAM won’t be there. Remember microwave ovens from 30 years ago? 2 electromechanical switches: power and timer. That’s all that is needed. And look at modern microwaves now… Interesting how much RAM they have already. 64 KiB? 8 MiB? More?

This page from STMicroelectronics suggests a microwave microcontroller would have about 40 KB of RAM and 256 KB of flash storage.
I am assuming this is for a relatively mainstream microwave without a bloated interface and ads.
Although it seems there are mutiple microcontrollers for different components.
