Laptop memory upgrade

[Nemesis]

i was browsing some laptops and i read that some of them had usr accesible memory sockets (SO-DIMMs) located on da under-side of da machine. does this mean that 1 can upgrade da memory by adding chips 2 these sockets? and r these separate frm da regular sockets or just da regular sockets?

I think user accessible memory sockets are different from the usual ones. Atleast they look different from the normal DIMMs. SODIMMs are smaller in size ...........thats all i got.
