What is the difference between Registered SDRAM and Unbuffered SDRAM?
Registered SDRAM utilizes incoming address and control signals that are latched into a register during the leading edge of one clock cycle. On the leading edge of the next clock cycle, the signal is presented to the SDRAM components. This relieves the potential loading on the memory socket. The difference with the Unbuffered SDRAM is that the control signals are sent to the SDRAM component without a propagation delay (pipeline burst).
