The basic difference between Static and Dynamic RAM lies mainly in structure and work principal. •Firstly the main difference in the structure varies due to transistor and capacitor number and setting as just three to four transistors are required for a Dynamic RAM, but six to eight MOS transistors are necessary for a Static RAM. •Secondly Dynamic RAM memory can be deleted and refreshed while running the program, but in case of Static RAM it is not possible to refresh programs. •Data is stored as a charge in a capacitor in Dynamic RAM, where data is stored in flip flop level in Static RAM. •For refreshing a data another capacitor is required in case of Dynamic capacitor, but no refreshing option is available in Static RAM. •A Dynamic RAM possesses less space in the chip than a Static RAM. •Dynamic RAM is used to create larger RAM space system, where Static RAM create speed- sensitive cache. •Static ram is 4 times more expensive than Dynamic RAM. •Dynamic RAM consumes less power than Static RAM. •For accessing a data or information, Static RAM takes less time than Dynamic RAM. •Dynamic RAM has higher storage capacity. In fact it can store 4 times than Static RAM.
