“SmartMedia” cards are the latest consumer flash package that you can get without a controller. Everything else has one. Even SD cards do. SD cards may not have a very good wear leveling algorithm, they may not have a lot of memory to keep track of fancier remapping structures, but they do have some. SD cards have a little arm processor inside managing everything, because it’s far cheaper than not having one. That processor is responsible for self testing pretty much everything at the factory - the testing jig is mostly there to deliver power and wait for the card to map the good and defective flash regions all by itself.
