What does EPROM mean in computer?
Erasable Programmable Read Only Memory
EPROMs (Erasable Programmable Read Only Memory) and EEPROMs (Electrically Erasable Programmable Read Only Memory) may be “flashed,” or erased and written to multiple times. The term “flashing” derives from the use of EPROMs: flashing ultraviolet light on a small window on the chip erased the EPROM.

What is EPROM short answer?
EPROM (erasable programmable read-only memory) is programmable read-only memory (programmable ROM) that can be erased and re-used. Erasure is caused by shining an intense ultraviolet light through a window that is designed into the memory chip.
How does EPROM work?
EPROM(Erasable Programmable Read Only Memory) can be programmed and erased enabling them to be re-used. Erasure is accomplished using an UV (Ultra Violet) light source that shines through a quartz erasing window in the EPROM package. They can be programmed one time only, so these are used after the code is bug free.
When was EPROM invented?
Short for Erasable Programmable Read-Only Memory, EPROM is a non-volatile memory chip that was invented by Dov Frohman in 1971 while at Intel that can only be read.
What is the difference between EEPROM and EPROM?
The main difference between EPROM and EEPROM is that, the content of EPROM is erased by using UV rays. On the other hand, the content of EEPROM is erased by using electric signals. In EPROM, UV light is used to erase the EPROM’s content. In EEPROM, electric signal is used to erase the EEPROM’s contents.
What does EPROM look like?
EPROMs are easily recognizable by the transparent fused quartz (or on later models resin) window on the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.
What is EPROM data?
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-volatile.
What are the characteristics of EPROM?
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.
What is the full meaning of EPROM?
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-volatile.
What does ‘prom’ and ‘EPROM’ mean?
PROM stands for Programmable Read Only Memory while EPROM stands for Erasable Programmable Read Only Memory, and EEPROM stands for Electrically Erasable Programmable Read-Only Memory. Developer Wen Tsing Chow developed PROM in 1956; Dov Frohman developed EPROM in 1971; George Perlegos developed EEPROM in 1978.
What are the disadvantages of EPROM?
`EPROM` has higher static power consumption then EEPROM.
How does EEPROM and EPROM differ?
EPROM and EEPROM both are erasable and can be reprogrammed , but the basic difference between them is that EPROM is erased using Ultra violet rays whereas, EEPROM can be erased using electric signals. Let us discuss the differences between EPROM and EEPROM with the help of comparison chart shown below.
