In computing, double data rate (DDR) describes a computer bus that transfers data on both the rising and falling edges of the clock signal and hence doubles the memory bandwidth by transferring data twice per clock cycle. [1][2] This is also known as double pumped, dual-pumped, and double transition.

Feb 3, 2023 · Learn about double data rate (DDR) memory key concepts and applications surrounding this digital communication technique, where two data words are transferred during one clock cycle.

Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers.

6 days ago · DDR, short for double data rate, was introduced in 2000 as the next generation following SDRAM. DDR transfers data to the processor on both the downbeat and upbeat of the clock signal, so twice per cycle.

Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of each other, and many motherboards use both by using DDR memory in a dual-channel configuration.

Double Data Rate (DDR) is a type of memory technology used in computers and other electronic devices to increase performance. Learn about the benefits of DDR and how it works at cadence.com.

Apr 8, 2025 · What is DDR? DDR, or Double Data Rate, is a type of Synchronous Dynamic Random Access Memory (SDRAM) that improves upon traditional SDRAM by doubling the data transfer rate without increasing the clock frequency.

Oct 12, 2016 · Dual-rank is slightly faster performance-wise (up to 4%), but also loads the memory controller more. One dual-rank module puts almost as much stress on the memory system as two single-rank modules! This can become an important factor once the DDR speed approaches certain limits. What is the memory system?

Apr 3, 2019 · The most common choice for main memory is dual data-rate synchronous dynamic random-access memory (DDR SDRAM or DRAM for short), because it is dense, has low latency and high performance, offers almost infinite access endurance, and draws little low power.

The NVIDIA (R) nForce (TM)2 DualDDR memory architecture optimizes system performance by increasing bandwidth and reducing memory latency.
