What happens to the IC at -20 degrees Celsius?

I've observed most chips specify -20C (-4F) as the "cold" end of their operating range. So what exactly happens at that threshold or below?

 

Does the chip go inert like lithium batteries returning to functionality retaining its data after warming back up again? Does the chip lose its data when it gets too cold? Is chip and data retention reliability on a curve in this context? deploy outdoors

 

I need to deploy tags outdoors; several use cases one of which is surface mounted to the glass window or door of a storefront and the other use case will deploy tags embedded in cast resin attached to objects outdoors, notably in Wisconsin, USA.
