The innards of an old Kingston 4GB USB stick that doesn't work properly any more. (It's detected at first, but then keeps getting reset and spewing errors a few seconds later.)

I don't know what I was expecting, but there's not much to see other than the flash controller, flash chip, and the USB connector.

Close-up photo of the top side of the green PCB extracted from a dead 4GB USB stick. The USB-A male connector is at the top, and the flash chip labelled "9904286 460.A00LF" and "4210965 6157391" is at the bottom, roughly equal in size, with 24 pins each on the top and bottom edges. There's a rectangular silver component in the middle whose label is unreadable. Other than that, there are some labels like R4/C3 printed on the PCB.Close-up photo of the underside of the same PCB, this time with the SK6211 flash controller chip visible in the centre, with 12 pins on each of its four sides. The reverse side of the PCB underneath the flash chip is the largest area visible, with printed labels like U3, R7, BC4, etc.
