Buffered Memory

A type of memory in which the modules have extra chips (registers) that delay data transfers to ensure accuracy.

Dual-Channeling

A memory architecture that increases the data transfer speed by allowing two memory modules to be accessed simultaneously.

Double-Sided Memory

A single memory module that contains two memory modules in one container (two banks). Data is still sent to the CPU 64 bits at a time. Some use the terms single-sided and double-sided to describe memory modules that have chips on one side (single-sided) or both sides (double-sided). Another name is double-ranked memory.

DDR4L Module

A type of DDR4 RAM (Random Access Memory) that operates at a lower voltage, offering energy savings while maintaining DDR4's high performance and speed.
