Answer: NVRAM(Non-volatile random-access memory)
Explanation:Non-volatile random-access memory(NVRAM) is the memory that has a non-volatile nature.It is used for retaining of the data even when the system gets switched off .
This memory uses the power source from the CMOS battery for executing the functions. It is designed by using the pin configurations containing 24 pin in DIP(Dual inline package). So the situation mentioned in the question of storing the changes will appear in the NVRAM.
