Different Types of RAM

Posted on/at 10:16 PM by bikram

There are three types of ram in the market.
1. SD RAM
2. DDR RAM
3. RD RAM

SDRAM (Synchronous Dynamic Random Access Memory)


SDRAM is a memory which is synchronized interface. It wait for a clock signal before responding to control inputs and then synchronized with the computer system bus. It has 168 pin, 3.3 volt, 66 MHz speed and 2 notchs points. This RAM is very slow performance that is why it is replaced by the fastest performance RAM.






DDR RAM (Double Data Rate Synchronous Dynamic Random Access Memory) 

Basically DDR RAM are double the rate of data transfer then the S DRAM. Three types of DDR RAM are found in the market
1. DDR1
2. DDR2
3. DDR3

DDR1



Speed                      400 MHz (up to)
Power                     2.5 volt
Pin No.                    184











DDR2

Speed                      800 MHz (up to)
Power                     1.8 volt
Pin No.                    240











DDR3

 Speed                                                          
Power
