I am not certain of how this motor retains that memory. But, the BBRAM IC that i spoke of looks like a typical IC, except it is "fatter" (taller and wider). The lithium battery cell is actually built into the IC so there wouldn't be a separate battery like a coin cell type on the board. I really am grasping at straws on that idea as I don't know how the memory is retained. I honestly would think that they would use some sort of EEPROM instead, but I would think that an EEPROM would be rare to fail so soon, so that is why I questioned if they might have incorporated a BBRAM. It was a thought anyhow.
