Double Data Rate Synchronous Dynamic Random-Access Memory

Double data rate synchronous dynamic random-access memory is a family of dynamic random-access memory technologies that transfer data in synchrony with the clock and use both clock edges to increase bandwidth.

The name DDRx refers to generations such as DDR3, DDR4, and DDR5.

This kind of memory is commonly used as main memory.
