One is for storing a program, usually a simple program like the BIOS in a computer or the application that runs a microcontroller. The EPROM device is programmed by forcing an electrical charge on a small piece of polysilicon material (called the floating gate) located in the memory cell.Īn EPROM is an erasable memory device that can store a small amount of data. Parallel Port Eprom Programmer contains a GNU/Linux driver thatcontrols the eprom programmer throught the parallel port and a toolwhich allows reading and …ĮPROM (UV Erasable Programmable Read Only Memory) is a special type of ROM that is pro- grammed electrically and yet is erasable under UV light.
