Hello, Today we learn What is DDR RAM & What are the Types of DDR RAMS.
In this post, I will define DDR RAM & the Full form of DDR RAM.
This Article is Best on the whole internet.
If you read this article carefully you will know all about DDR RAM
I Guaranteed you, after reading this article you will not need to read any other Articles. In fact, our reader’s satisfy in this blog post.
What is the Full Form of DDR RAM?
The full form of DDR RAM is Double Data Rate Dynamic Random-Access.
To understand you, the complete full form of each word of the DDR is given in the table below.
D | Double |
D | Data |
R | Rate |
What is DDR RAM?
DDR RAM ( Double Data Rate ) is the advance version of SDRAM (Synchronous Dynamic Random-Access Memory).
DDR is a very fast computer memory that transfers data on both the rising and falling edges twice as fast as compared to SDRAM chips.
Due to the different use of the clock signal, DDR RAM is capable of transfer twice at the same time.
Double Data Rate also knows as double pumped.
DDR RAM also Knows as DDR1 RAM.
The average power consumption DDR RAM is 2.5 to 2.6 volt per 512 MB.
I Hope you understand DDR RAM.

Different Types of DDR RAM
There are five types of DDR SDRAM is given below.
- DDR1 SDRAM
- DDR2 SDRAM
- DDR3 SDRAM
- DDR4 SDRAM
- DDR5 SDRAM
1.) DDR1 SDRAM
DDR RAM ( Double Data Rate ) is the advance version of SDRAM (Synchronous Dynamic Random-Access Memory).
All Detail About DDR1
- Developer - Samsung
- Type - SDRAM
- Release date - 1998
- Voltage - 2.5 to 2.6 Volt
- Clock Rates - 100 to 200 MHz
2.) DDR2 SDRAM
DDR2 RAM also transfers data twice at the same time. But DDR2 is capable of transferring data faster than DDR1.
Because the upgrade version of DDR1 is DDR2.
- Developer - Samsung JEDEC
- Type - SDRAM
- Generation - 2nd Generation
- Release date - 2003
- Voltage - 1.8 to 1.55 Volt
- Clock rate - 100 to 266 MHz
- Cycle time - 10 to 3.75 ns
- Bus clock rate - 200 to 533 MHz
- Transfer rate - 400 to 1066 MT/s
3.) DDR3 SDRAM
DDR3 RAM also transfers data twice at the same time. But DDR3, is capable of transferring data faster than DDR2 and DDR1.
Because the upgrade version of DDR1 and DDR2 is DDR3.
- Developer - JEDEC
- Type - SDRAM
- Generation - 3rd Generation
- Release date - 2007
- Voltage - 1.5 to 1.35 Volt
- Clock rate - 400 to 1066 MHz
- Transfer rate - 800 to 2133 MT/s
4.) DDR4 SDRAM
DDR4 RAM also transfers data twice at the same time with high bandwidth. But DDR4, is more capable of transferring data faster than DDR1, DDR2 and DDR3.
Because the upgrade version of DDR1, DDR2 and DDR3 is DDR4.
- Developer - JEDEC
- Type - SDRAM
- Generation - 4th Generation
- Release date - 2014
- Voltage - 1.2 Volt
- Clock rate - 800 to 1600 MHz
5.) DDR5 SDRAM
DDR5 RAM also transfers data twice at the same time with high bandwidth. But DDR5, is more capable of transferring data faster than DDR1, DDR2, DDR3 and DDR4.
Because the upgrade version of DDR1, DDR2, DDR3 and DDR4 is DDR5.
- Developer - JEDEC
- Type - SDRAM
- Generation - 5th Generation
- Release date - July 14, 2020
- Voltage - 1.1 Volt
- Clock rate - 1600 to 3200 MHz
Which device were Use of DDR RAM?
Most of the devices used DDR RAM technology and most battery operated device used DDR RAM because DDR technology consume less power.
These devices was used DDR RAM, is given below.
- Mobile Phone
- Handheld Device
- Digital Audio Player
Advantages of DDR RAM
- DDR RAM speed is faster than SDRAM.
- DDR RAM transfers data on both the rising and falling edge of a clock cycle.
- DDR RAM consumes very less power.
History of DDR RAM
In 1997, Samsung was the first company in the world to create a DDR memory prototype.
Samsung launched the world's first commercial DDR SDRAM 64 Mb chip in June 1998.
In August 2000, the world's first retail PC motherboard used DDR SDRAM.
