DRAM is a type of RAM that uses each bit of information in a single capacitor within the integrated circuit,since the real capacitor leak charges therefore information stored eventually fades and is required to refresh periodically.

How many types of ram r there?

There are three main types. DRAM - Dynamic Ram, which is the RAM in most computers. It's called Dynamic because there is a need for circuitry in the computer to constantly refresh the data. It will lose all data if power is removed. SRAM - Static Ram. Not as common but used to be used in laptops and portable devices. Called Static as you don't have to refresh all the time, but it does lose the data if you turn the power off. It is lower power than DRAM, but not as high capacity Flash RAM - though there are lots of names for this. Used in USB keys etc. It saves data even after the power is turned off. Access to it is a lot slower than DRAM.


Differentiate between static ram and dynamic ram in tabular form any two differences?

· Static RAM: No refreshing, 6 to 8 MOS transistors · Dynamic RAM: Refreshed periodically, 3 to 4 transistors. · Static ram is more reliable · Dynamic ram is less reliable · Static ram is more expensive · Dynamic ram is less expensive · Static ram can store its data when computer is turned off · Dynamic ram looses data when computer is turned off. · A static memory cell takes a lot more space on a Chip than a dynamic memory cellby syed9230088668199
