Freeze the video at 1:47 and you'll see K352 4SDYU from STMicroelectronics. Dug a little and came up with M24SR16-YDW6T/2 which can be found in DigiKey here: https://www.digikey.com/products/en?keywords=M24SR16-YDW6T%2...
That one is only a 2Kb though. They also make an 8Kb 4SFYU: https://www.digikey.com/products/en?keywords=M24SR64-YDW6T%2...
