ST refers to a technology called muxed PSRAM.
As far as I know, this simply means, that the data and address signals share the same IO pins.

All simple and good, but my question is, could someone point me to a PSRAM, which actually is compatible to such an arrangement? I googled a lot, but all I could find was a US patent about this technology.

BTW, my requirement is to drive a TFT (320x240) screen with ST's LTDC (Hsync, Vsyc etc). I would like to be able to use an LQFP100 package, which leaves me the opportunity to have a 8 bit muxed PSRAM as a frame buffer for the display.

See attached STM32Cube file.

Thanks a bunch!
