Swapping flashed SPI Flash chip to a new ESP8266

From what I understand, there's no programmable ROM on the esp8266. Does that mean that the esp does not store any information regarding flashes either? If that is the case, theoretically, we could flash the SPI Flash memory using another esp and move it to a new one, correct?

Thanks.

afaik the SDK stores RF calibration data to a flash sector. That may cause issues, if the calibration is for a different device.

You probably should erase that sector before transplantation.
