Different Types of RAM
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.
1. SD RAM
2. DDR RAM
3. RD RAM
SDRAM (Synchronous Dynamic Random Access Memory)
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

Nice and very helpful information i have got from your post. Even your whole blog is full of interesting information which is the great sign of a great blogger.
Toshiba - Satellite Ultrabook 14" Laptop - 4GB Memory - 500GB Hard Drive - Ice Blue (U945S4130)
Toshiba - Satellite 15.6" Laptop - 4GB Memory - 640GB Hard Drive - Mercury Silver (L855S5136NR)
Really worthwhile information and great to see that how technology has been revolutionized, now RAM coming in microchips with high speed.
Great piece!
