Type Of RAM

   Type Of RAM :-
    
RAM is the main memory of the computer. It holds the data until the system is turned off.once the system is switched off the data is lost. There are two types of Ram , Static RAM and Dynamic RAM.

Static Random Access Memory(SRAM) :-

1) Stores data till the power is supplied
2) Uses an array of transistors for each memory cell.
3) Does not need refreshing the memory cell after each reading of the transistors.
4) Data access is faster
5) Consumes more power
6) It is Expensive.

Dynamic Random Access Memory (DRAM) :-

1) Stores data only for few milliseconds even when power is supplied.
2) Uses a single transistor and capacitor for each memory cell
3) Needs refreshing the memory cell after each reading of the capacitor
4) Data access is slower
5) Consumes less power
6) Less Expensive
