Also, Ambiq Micro has a 2MB MRAM (+2.75MB SRAM) processor https://www.top-electronics.com/en/apollo4-blue-plus-192-mhz... that can run on solar power (it uses ~5uA/MHz, Cortex M4) and Andreas Eriksen got LISP text editor to run on 384K RAM with the Apollo3 https://hackaday.io/project/184340-potatop and 4'4" Memory In Pixel Display.
