Hello and welcome to Bleepingcomputer.
According to these specs from Toshiba's web site it only shows 2 GB as being the default amount of RAM.http://www.csd.toshiba.com/cgi-bin/tais/su...mily=1073768663
It does not specify the brand name of RAM it has, or how many slots are being used.
Best way to know is to open the little access panel on the bottom of the laptop to find out if there are two 1 Gb sticks or not.
My personal belief is that there is most likely two sticks, each at 1 Gb in the slots, totaling 2 Gb.
