XL330S Memory - possible to expand?

[AzureJohn]

My XL330S has 1 G of memory. Not enough.

I opened it up to see if I could splice in a micro-SD adapter, ala this post

But, after I got my unit apart, I could not tell where the memory chip is.

Could someone look at the last two photos on this link

and tell me which is the memory, and perhaps even if it is possible to splice in another chip?

The closest thing I've seen is this post. It's for a One 3rd edition, but might give you some clues. The XL330s runs similar software as the One 3rd edition, so I would guess that the software will accept an Sd adapter just like the One 3rd did.

I've never opened up a 330s, but my guess is that the memory is one of the bigger chips. Just google the number on each chip starting with the largest until google says the chip is 1GB flash ram.
