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. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM and DDR5 SDRAM.

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology.

Oct 1, 2018 · This article briefly overviews the major differences between the different types of DRAM including Synchronous Dynamic Access Memory (SDRAM) and the various types of Double Data Rate (DDR) topologies (i.e.: DDR2, DDR3, DDR4).

From the extreme temperature and performance needs of industrial and automotive applications, to the exacting requirements of enterprise systems, we have the right DRAM solution for your …

6 days ago · What’s the difference between SDRAM, DDR, DDR2, DDR3, DDR4 and DDR5? Discover and compare the different generations of RAM with Crucial.

Double Data Rate 4 Synchronous Dynamic Random-Access Memory (DDR4 SDRAM) is a type of synchronous dynamic random-access memory with a high bandwidth ("double data rate") interface.

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.

One of the big changes though when DDR came out with the specification of DIMM and SODIMM chip types, for desktops and laptops respectively. DDR SDRAM were originally produced at the 133MHz clock rate with a 7.5,6 and 5ns/cycle latency.

Feb 10, 2021 · DIMM chips carry DDR SDRAM for upgrading RAM on a PC. This article discusses the more modern versions of volatile RAM, including general points on DDR SDRAM standard and how it evolved.

Jul 9, 2024 · Double Data Rate (DDR) memory enhances the capabilities of Synchronous Dynamic Random Access Memory (SDRAM) by significantly boosting data transfer speeds between the processor and memory.
