What is DDR RAM and how does it work?
DDR RAM, or Double Data Rate Random Access Memory, is a type of computer memory that temporarily stores data for the computer’s processor to access. It works by transferring data on both the rising and falling edges of the clock signal, which allows for twice the data transfer rate of single data rate RAM. This is achieved through the use of a clock signal that oscillates at a specific frequency, and the data is transmitted in synchronization with this clock signal. The DDR RAM module consists of multiple memory chips that are connected to a printed circuit board, which provides the necessary connections for the memory to communicate with the computer’s processor.
The evolution of DDR RAM has led to significant improvements in its performance and capacity. The first generation of DDR RAM, known as DDR1, had a data transfer rate of 2.5 GB/s and a clock speed of 100 MHz. Subsequent generations, such as DDR2, DDR3, and DDR4, have increased the data transfer rate and clock speed, with the latest generation, DDR5, offering a data transfer rate of up to 51.2 GB/s and a clock speed of up to 6400 MHz.
