    An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non … See more

    What does EPROM stand for?
    EPROM stands for Erasable-Programmable ROM. The ICs hold code, often an auxiliary program such as an application, utility or game which can be loaded immediately on startup. Sometimes they were used to house the bootstrap code and/or the BASIC interpreter in old microcomputers although this function was often more commonly provided by mask ROMS.

    What are the disadvantages of EPROM?
    Disadvantages of Erasable Programmable Read Only Memory (EPROM) It consumes high static power. Not flexible to delete any specific byte, beyond of all data is deleted. EPROM takes more time to delete data. Advantages of Electrically Erasable Programmable Read Only Memory (EEPROM) Ways of deleting data is electrical and instant.

    How can an EPROM go bad?

    EPROMS might go bad in old cars?"Bit Rot"

    1. The charges on the storage cells leak away over time and your program gets corrupted.
    2. The chip itself begins to fail due to things like "metal migration". Something that Beau has talked about here...

    What is the function of EPROM?

    Some of the advantages of EPROM are as follows:

    • EPROM is non-volatile so it retains its memory even without power. So no external memory is required.
    • EPROM is quite effective.
    • EPROM is reprogrammable i.e. the data in the EPROM can be erased and reprogrammed.
