Yes, integrated memory can be dual channel.

I understand how to verify once you own it, but I'm looking for a lighter option right now. My current laptop has one soldered chip and one SODIMM port. Most modern laptops with two SODIMM slots support dual-channel memory, but most thin models come with built-in RAM. I reached out to Lenovo and Dell about specific models and they all mentioned single-channel support, so I wondered if it's even feasible.
