#157327 - the reason
Responding to: ???'s previous message
I'm allmost sure that in the deep past existed micro , which can load program from serial memory. Unfortunatelly i can't remember which one.
There are quite a few, e.g. some (non-51) from Cypress.
These DO NOT "execute from serial memory", the reason they operate with a serial code memory is that because of the slowenness of flash they execute from fast RAM. On power up the serial memory is copied to RAM and then forgotten. I think the "wide bus flash" is preferable, but that is totally subjective.
