Abstract :
A series pipelined CAS latency control with voltage-controlled delay line that extends maximum data rate to 2.5Gb/s/pin at 1.7V, is presented. Other schemes applied in the DLL are dual loop control that increases power noise immunity and LPDCC that achieves low power consumption. All these schemes are implemented in a 8M times 32 device using a 0.10 mum DRAM process
