摘要: In a synchronous DRAM, internal clock signals in synchronism with fed from an external unit are generated by PLL circuit or DLL to eliminate signal delays. order provide dynamic RAM that is capable of stably operating over wide range frequencies; change-over provided which changes the variable frequencies delay time based upon mode-setting information unit.
