![]() ![]() On the contrary, the RAM memory is volatile. It can only be erased electrically whether it’s internal within a microcontroller (By Code) or external IC (By Electronic Device). Which means it won’t lose the data contents when the power goes OFF. You should also know that EEPROM memories are non-volatile. The EPROMs had to be exposed to ultraviolet light for a convenient time period in order to get fully-erased. A typical EPROM has a window on the top side of the IC to allow the ultraviolet rays to reach the memory cells in order to erase the memory. Which was the previous technology in this area. ![]() The EEPROM memory devices have evolved from the old EPROM memories. This kind of memory devices is re-programmable by the application of electrical voltage and can be addressed to write/read each specific memory location. 5 Implementing EEPROM W/R Firmware DriverĮEPROM, pronounced as Double-E-PROM, stands for Electrically Erasable Programmable Read-Only Memory.
