What is DDR1 RAM


After SDR RAM proves what a RAM could do inside a computer system, computer scientists and engineers wanted to achieve higher speeds in a computer. They kept researching and trying to upgrading the features inside the computer systems and the components of the computer system.

What is DDR1 RAM?

DDR1 RAM is the very first initiative of the DDR family and the technology of it's kind. SDR RAM was in a separate data which was single data rate which stood by the term SDR. DDR stands for Double Data Rate. Which means twice faster data rate.

Starting from 1996 JEDEC who is an individual semi conductor manufacture developed the DDR or double data rate RAM standard and finalized on 2000. DDR SDRAM is an interface that makes possible the higher transfer rates with more strict control and timing of data flow and the clock signals. To achieve what so ever in DDR SDRAM, implementation of phase locked loops and self calibration time accuracy was implemented.

Due to the advancements in the interface alone, the double bus bandwidth without increasing the clock frequency was possible. By keeping the clock frequency low or prior states, DDR SDRAM was capable to reduce the signal integrity requirements of the circuit board and the memory controller. 

There were two types of interfaces that were introduced into the market to support the DDR to wide range of computing products. DIMM also known as dual in line memory modules were introduced to support the desktop computers and SO-DIMM also known as small outline dual in line memory module introduced to support mobile computers such as laptops which were in the market.
