Erasable Programmable Read-Only Memory(EPROM)
EPROM is reorganized. Whereas PROM is more expensive, EPROM is non-volatile. Erasable Programmable Read-Only Memory is for erasing and rewriting the programming. EPROM is more economical than PROM. The data stored in EPROM can be erased and reprogrammed again by ultraviolet light. Reprogrammed of it is limited. Before the era of EEPROM and flash memory, EPROM was used in microcontrollers.
Advantages of Erasable Programmable Read-Only Memory
- In Erasable Programmable Read-Only Memory, programme be erased and rewritten.
- The nature of EPROM is non-volatile.
- EPROM is more economical than PROM.
- It Delete all of the prior data in order to reprogram it.
Disadvantages of Erasable Programmable Read-Only Memory
- EPROM cannot erase a single byte on its own. if you delete a single byte, all of EPROM’s bytes are also destroyed.
- Data deletion from the EPROM Memory Chip requires extra time.
- Changing the stored data when system needs change is quite costly.
- Users can not add information frequently and guidelines based on what they need.
Different Types of ROM
ROM (read-only memory), and flash memory are examples of non-volatile memory. Whereas volatile memory is a temporary memory. In this memory, the data is stored till the system is capable of, but once the power of the system is turned off the data within the volatile memory is deleted automatically.
