Has someone succeeded extending RAM on the nRF53 series?

Hi, although there are many guides and stories about attaching the nordic to external storage NVM, there aren't infos about doing the same with RAM. 

I even found some threads recommending usage of cheaper SD-Cards, but this is crazy. I am talking about RAM here.  I understand NVMs can be misused for this, but this can not be considered for serious work, considering wearing out.  I am sure there are competitors offering chips able to extend their ram with SPI compatible PSRAM but I don't get why it may not be possible to achieve this with nordic chips. Any suggestions?

You don't supply many details, but I have had some success with Everspin products. They don't have great $/bit but they have virtually unlimited read/write capability.
