For firmware, usually there's a small flash memory chip on the motherboard where low-level code is stored in order to control the hardware. I'm not sure how the PS3 implements it, but when "flashing" the memory you always get a warning not to turn-off the power as that would interrupt the sequence and render the device unusable until it was serviced and the memory reset.
