Ceg 453653 eprom handout instructions for programming tutor eproms the tutor code will be programmed into two 2764 eprom chips from files which reside in the eprom directory of the hard disk on the pc nearest the ta office door. Eprom and eeprom can be erased and reprogrammed again but at a very slow speed. An eprom rarely erom, or erasable programmable readonly memory, is a type of programmable readonly memory prom chip that retains its data when its power supply is switched off. This very high speed device allows the most sophisticated microprocessors to run at full speed without the need for wait states. This is accomplished by sending the required command, address and data serially one bit at a time over single pins instead of the multiple pins of a parallel part.
