Difference Between Buffered and Unbuffered RAM

The main difference between buffered and unbuffered RAM is that the buffered RAM contains a register between the DRAM and the memory controller while the unbuffered RAM does not contain a register between the DRAM and the memory controller.

RAM stands for Random Access Memory. It is a nonvolatile memory that requires a constant flow of power to retain data. Usually, the programs are stored on the hard disk. It requires more time for the CPU to access the hard disk. Therefore, at the time of execution, the programs are loaded into RAM. The capacity of the RAM is a considerable factor in determining the performance of the system. There are mainly two types of RAM called SRAM and DRAM. SRAM is a fast memory built using flip flops. DRAM is fast but not as fast as SRAM. Other than these two types, RAM can also be categorized as Buffered and Unbuffered RAM.
