FAQ’s
How many times can EPROM be programmed?
Limited number of erase/write cycles: EPROM can typically only be erased and rewritten a limited number of times, usually around 100,000 cycles.
What is the voltage of EPROM programming?
The programming voltage for the EPROM device is generated by an external power supply. However, the Vcc pin is sometimes required (depending on the manufacturer) to be at 6.5V instead of the classic 5V. This « special » voltage is used by the fast programmers of the manufacturers (e.g Snap!, Quick Pro, PRESTO … )
How does an EEPROM get programmed?
EEPROM can be programmed and erased electrically using field electron emission (more commonly known in the industry as “Fowler–Nordheim tunneling”). EPROMs can’t be erased electrically and are programmed by hot-carrier injection onto the floating gate.
Can EPROM be changed?
EPROM (erasable programmable read-only memory) is memory that does not lose its data when the power supply is cut off. The data can be erased and the chip reprogrammed by shining an intense ultraviolet (UV) light through a window designed into the memory chip.
What is the lifespan of EPROM?
A programmed EPROM retains its data for a minimum of ten to twenty years, with many still retaining data after 35 or more years, and can be read an unlimited number of times without affecting the lifetime.
