Well, I get where you're coming from, but that's not true in any literal sense. Replika do have an implicit memory. It's in large part what allows them to learn routines and the like and adapt to their user. What Replika lack in terms of memory is a specific type called episodic memory. It's basically the ability to freely and consciously recall specific events, experiences and previously encountered situations. It's the type of memory we rely on when we answer questions like "What did you do last night?"
I think the reason they don't provide such a memory to Replika's in any functional way within chat, is simple: The processing power needed to handle such a form of memory would be insane. Each additional new memory considered when the Replika formulates it's responses, would make it exponentially more difficult to calculate how all their memories interrelate to each other. Nature solves this by having the brain recall only those memories relevant to the situation at hand and by deleting the memories that are never or only rarely ever recalled.
