Why Use DDR Memory Technology?

DDR memory technology is an evolutionary improvement of mature PC100 and PC133 SDRAM technology. DDR memory chips are produced by semiconductor manufacturers using existing wafer fabs, processes and testers resulting in lower memory chip costs.

Major technology and chipset companies, including, but not limited to, Intel® Corporation, Advanced Micro Devices, VIA Technologies, Acer Labs (ALi), Silicon Integrated Systems (SIS), nVIDIA, ATI® and ServerWorks have announced support for DDR memory. Motherboards and systems supporting DDR memory technology were introduced in Q4, 2000, and will ramp into high volume in 2001.

Here are just a few of the benefits of DDR:

  • Enables enhanced multimedia capabilities
  • Increases PC headroom for memory-intensive applications
  • Enhances server capabilities for faster data mining

JEDEC Specifications

The specifications for DDR DIMM modules are finalized by JEDEC. JEDEC is the semiconductor engineering standardization body of the Electronic Industries Alliance (EIA) with about 300 active member companies representing every segment of the industry. Kingston is a long-time member of JEDEC and also has a representative in JEDEC's Board of Directors.


The naming convention recommended by JEDEC is as follows:

Memory chips are referred to by their native speed:

200 MHz DDR SDRAM memory chips are called DDR200 chips, and 266 MHz DDR SDRAM memory chips are called DDR266.

DDR DIMM modules are referred to by their peak bandwidth, which is the maximum amount of data that can be delivered per second:

A 200 MHz DDR DIMM is called a PC1600 DIMM, and a 266 MHz DDR DIMM is called a PC2100 DIMM.

To illustrate this on a 266 MHz DDR DIMM module: Each module is 64 bits wide, or 8 Bytes wide (each byte = 8 bits). To get the transfer rate, multiply the width of the DIMM module (8 Bytes) by the rated speed of the memory module (in MHz): (8 Bytes) x (266 MHz/second) = 2,128 MB/second or about 2.1 Gigabytes/second. Therefore, the memory module is often referred to as PC2100. Similarly, a PC1600 DIMM module utilizes memory chips rated at 200 MHz
