FYI, for anyone who comes across this post in the future, I was able to get the memory chips out but it was a right royal @#$)(. Had to use two screwdrivers and a small 90-degree pick. Lever one small screwdriver behind the memory chip I was trying to remove and against the chip behind it, while using the pick to reach in from behind the chip and push the little clip down, while using a larger screwdriver to "twist" at the bottom of the chip, between it and the socket, to rotate each edge out. Like in this picture, I would be rotating the large screwdriver clockwise to lift that edge out of the socket.
In other words, it is possible to do this without damaging the socket, but what a PITA! :-/
