In SLI or Multi GPU mode, is memory shared (i.e do both 2GB cards become a 4GB configuration)?


No, each GPU maintains its own frame-buffer so you will not double your memory. Rendering data, such as texture and geometry information, is duplicated across both cards.  This is also the case with Multi-GPU mode when using a single GeForce 7950 GX2, 9800 GX2,  GTX295, GTX 590 and GTX 690 based card.
