The SSD certainly isn't in the same package as the CPU and GPU, so your comment is simply wrong, given the question that was actually asked. Whether the RAM is on-package or not is irrelevant to the question asked further upthread. It is soldered. Neither the RAM nor the SSD can realistically be upgraded after the fact. That's the answer to the question.
I don't understand the purpose of your comment.
