I just captured the FLASH and DRAM difference. Make sure why we use these memories in our daily life.

|
Capacity
|

|
Holds more data
|
Resides
|
Sits in Main memory of CPU
|
Sits in Hard drives
|

|
Slow
|
Cost
|

|
Low-Cost

All our configurations get stored in Flash, so that after reboot also it will come up with old configurations.
The executable will be loaded via flash.
User Traffic statistics get stored in DRAM, since we don't want to preserve.
