In the late 1980s IBM had built DRAMs using a dual-edge clocking feature and presented their results in the International Solid-State Circuits Convention in 1990. Samsung demonstrated the first DDR memory prototype in 1997, and released the first commercial DDR SDRAM chip (64 Mbit) in June 1998, … See more 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rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits See more DDR (DDR1) was superseded by DDR2 SDRAM, which had modifications for higher clock frequency and again doubled throughput, but … See more Modules To increase memory capacity and bandwidth, chips are combined on a module.

WebBecause of these differences, DDR2 modules have a different key (a notch in the connector) to prevent them from being inserted into an incompatible socket. This means that DDR2 memory modules will only fit into computers with motherboards designed to support DDR2 memory and will not fit into computers with motherboards designed to support … WebAug 5, 2024 · Here's how to tell the difference between types of DDR memory: DDR: These modules have 184 pins, and the notch is near the center. DDR2: These modules have 244 pins, and the notch is near the center. DDR3: These modules have 240 pins, and the notch is offset to one side. DDR4: These modules have 288 pins, and the notch is near the … WebDDR-200 (also called PC1600) runs at 200 MT/s (million transfers per second), or 1600 MB/s (megabytes per second).
