The 400 Series cameras work with any Intel or ARM processor, and a USB 3 or USB 2 port (though the camera's capabilities are greatly limited on USB2). They are designed to work with multiple different hardware platforms, whether low-spec or high-spec, by not being highly specific about hardware requirements.
This flexibility is made possible because the camera contains a component called the Vision Processor D4 that processes data inside the camera instead of having to have a GPU inside the computing device process it.
As far as I know there is not a minimum memory requirement. I am reminded of the phrase "It runs on a potato". However, you will need sufficient memory to run the computing device's operating system and the particular software application / script that you are using with the camera.
