Operating Frequency difference between QDR-II/DDR-II and QDR-II+/DDR-II+

Last Updated: 12/29/2011

Question: Is there a difference in the frequency of operation between QDR-II/DDR-II and QDR-II+/QDR-II+?


Yes. QDR-II/DDR-II frequency range, when the DLL is on, is 120MHz-300MHz. QDR-II+/DDR-II+ frequency range, when the DLL is on, is 120MHz-400MHz (for 90 nm technology devices) and hen the DLL is on, is 120MHz-333MHz. QDR-II+/DDR-II+ frequency range, when the DLL is on, is 120MHz-550MHz (for 65 nm technology devices)
