The logical state is established by charging, through an electrical present, all bits whose states are to be changed from the default state. EPROMs may be erased and reprogrammed as a outcome of the electrical charge on the bit areas could be bled off [i.e. Reset to the default state] by publicity to ultraviolet gentle through the small quartz window on top of the IC. After programming, the IC’s window have to be covered to forestall exposure to UV mild till it is desired to reprogram the chip. An EPROM eraser is a tool for exposing the IC’s circuits to … Read More
