The most common electronic device is the MOSFET,[29][32] which has become the most widely manufactured device in history.[33] Common solid-state MOS devices include microprocessor chips[34] and semiconductor memory.[35][36] A special type of semiconductor memory is flash memory, which is used in USB flash drives and mobile devices, as well as solid-state drive (SSD) technology to replace mechanically rotating magnetic disc hard disk drive (HDD) technology.

History of electricity
In 1887, Heinrich Hertz[19]:843–44[20] discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for "his discovery of the law of the photoelectric effect".
