I am working on a Z80 replica in 180 nm and would love some ideas and sketches for the Free and Open Source Silicon (FOSSi) Z80 logo - to "bake" it directly into the silicon on the chip!

Here are some cool examples of the chip art: https://hackaday.io/page/11717-chip-graffiti-hilarious-arts-...

This Z80 replica will be manufactured with the new https://wafer.space service.

Is it possible to place some low power SRAM and flash/EEPROM on the same die as well?

It is a very good idea about SRAM! Around 16KB of SRAM can fit on the die (Wafer.Space provides 20 mm^2 area per chip) - that could be useful for both fixing old computers like ZX Spectrum and handy for turning Z80 into a tiny MCU.

However Flash/EEPROM is currently out of the question. I don't know of any open-source versions available. That would have been a very serious undertaking on it's own!
