Your laptop uses eMMC memory which is embedded on the motherboard. You can neither remove it or upgrade it. Your best bet is to buy a decent SD card or external drive as a base of storage.

What he said above.

No you cannot.
I have a Asus Transformer with a similar (32GB) eMMC drive. It is what it is.
Add a 64GB or 128GB microSD card in whatever slot accepts it.
