Larger RAM modules have significantly higher capacity loads for their signal lines. Buffering reduces these loads, but increases latency.

* Unregistered RAM
* Registered RAM: Address and control lines are buffered, data lines are unbuffered
* Fully buffered RAM: All the lines are buffered
* Address buffered RAM: often used in large memory arrays
