What is mean by single sided and double sided type 2280 M.2 NVMe SSDs

Hi, that is mean by single sided and double sided type 2280 M.2 NVMe SSD? Are the Samsung 970 Evo/Evo Plus single sided or double sided?

Per the specs listed here, they are single sided....

I believe the 2TB models are double sided. It means there’s chips on both side rather than just one side. What this means for you is it may not fit in certain m2 slots which don’t have enough space or heat dissipation.
