FRAM71 is a device created by forum member Hans Br├╝ggemann. It fits the card reader slot of a 71B and provides non volatile RAM in 'gigantic' amounts (512 or 1024 KB, depending on hardware version). It is configurable and the maximum RAM available with a given configuration depends on what else is plugged into your 71B.

IRAM (Independent Random Access Memory) is just RAM memory that the 71 can address as a port. The FRAM71 can provide IRAM as explained above.
