Created page with "There should be enough memory on board to store flight software, payload data, health monitoring data,etc. And enough RAM to execute all the software. Different type of memori..."

New page

There should be enough memory on board to store flight software, payload data, health monitoring data,etc. And enough RAM to execute all the software. Different type of memories can be classified as follows :-
* '''Volatile memory: ''' It requires constant power to maintain the stored information. Example: [https://en.wikipedia.org/wiki/Static_random-access_memory SRAM(Static Random Access Memory)]
* '''Dynamic Memory:''' It is a volatile memory which also requires constant power to store information, it is periodically refreshed, or read and rewritten without modifications. Example [https://en.wikipedia.org/wiki/Dynamic_random-access_memory DRAM (Dynamic Random Access Memory)]. DRAM is less expensive than SRAM, but SRAM is much faster than DRAM
* '''Non-volatile memory:''' It will retain the stored information even if it is not constantly supplied with electrical power. For example [https://en.wikipedia.org/wiki/Flash_memory Flash], [https://en.wikipedia.org/wiki/EEPROM EEPROM (Electrically Erasable Programmable Read-Only Memory)] and magnetic memory (HDD).
