Abstract :
This paper presents the application feasibility of mixed mode PLL-DLL in DRAM. Jitter analysis of mixed mode PLL-DLL in DRAM environment has been carried out. According to the jitter type, this model can be used as pure PLL or pure DLL or a mixed PLL-DLL. It is observed that mixed mode PLL-DLL architecture can combine the advantage from both PLL and DLL to reduce jitter in DRAM.
