What type of screwdriver do I need to open the memory casing on a Fujitsu lifebook? They are super teeny screws

I need to replace the memory on my Fujitsu lifebook U series. I have tried to open it with the ordinary laptop screwdrivers but they are too big. Does anyone know what type I would need and where I could find one, please?

Hi,

It's normally called Torx screw driver and it's a six sided screw that can only be removed normally with that so called screw driver.
