Despite the potential of superconductor-based electronics to significantly impact the electronics industry – for example, a superconducting computer chip is a thousand times faster than the one within the laptop I'm using right now – they have not taken off the way some researchers anticipated. One reason may be that superconducting memory chips are just not dense enough; they can only hold up to 16 kilobits of information, compared to up to several gigabits delivered by other chips.
