Question

Memory chip NOVRAM is
1. Only ROM
2. Only RAM
3. Combination of EEPROM and RAM
4. Only PROM

Answer 1

Correct Answer - Option 3 : Combination of EEPROM and RAM

NOVRAM (Non-Volatile Random Access Memory):

• It is a type of memory that retains its contents when power is turned off.
• One type of NOVRAM is SRAM that is made non-volatile by connecting it to a constant power source such as a battery.
• Another type of NVRAM uses EEPROM chips to save its contents when power is turned off. In this case, NVRAM is composed of a combination of SRAM and EEPROM chips.

 

ROM type	Full form	Description
ROM	Read-only Memory	A ROM chip cannot be erased or rewritten.
PROM	Programmable Read-only Memory	A PROM chip cannot be erased or re-written.
EPROM	Erasable Programmable Read Only Memory	An EPROM chip can be erased with exposure to UV light.
EEPROM	Electrically Erasable Programmable Read Only Memory	EEPROM chips are also called Flash ROMs. An EEPROM chip can be erased and re-written without having to remove the chip from the computer.
