What is buffered memory?

Answer 1

Memory modules that utilize temporary storage areas (known as buffers) to help manage the data sent to the memory by the memory controller. Buffers act as current regulators keeping the amount of current flowing to and from the chips at optimal levels. The purpose of this is to allow for more memory chips on modules by keeping the memory from being overloaded by the chipset. It can also be used to allow more modules to be used in the system. Not all systems can use buffered memory; the type of memory required is dependent upon the computer's memory controller.

Buffered memory is an older term for registered memory.

However, some new large systems use "fully buffered memory". In normal registered/buffered memory only the control lines are buffered, in fully buffered memory the data lines are buffered as well.

Answer 2

Buffer memory refers to the temporary storage area for the generated or acquired data.
