What kind of memory modules include registers between the system’s memory controller and the module’s memory chips, registers that communicate in series with the memory controller and in parallel with the memory chips, easing the electrical strain on the memory controller?
- ecc
- non-parity
- buffered
- multi-channel

Buffered

Explanation:

 The buffered memory module is the kind register which include between the memory system controller and the chips. The buffered memory module is also known as registered memory module.

These registers are basically used in the communication with the series and parallel memory controller. The buffered memory module is basically contain register between the memory control and dynamic random access memory (DRAM).  

It basically placed on the less electrical load and also allow the single system for stable and electrical strain in the memory controller.
