Commonly referred to as a "Chip-Off" technique within the industry, the last and most intrusive method to get a memory image is to desolder the non-volatile memory chip and connect it to a memory chip reader. This method contains the potential danger of total data destruction: it is possible to destroy the chip and its content because of the heat required during desoldering. Before the invention of the BGA technology it was possible to attach probes to the pins of the memory chip and to recover the memory through these probes.
