The acronym LRDIMM (Load Reduce DIMM) indicates a specific type of RAM memory (of the Registered DIMM family) that replaces the memory register with an isolated circuit called Isolated Memory Buffer. This component buffers commands, memory addresses and data signals and isolates the host controller's memory chip. In practice, the physical host "reads" only the iMB chip upstream of the desk and allows an increase in storage capacity up to 100%.
