For operating frequencies exceeding 500 MHz, the timing margin of the I/O interface is critical and requires the data input-output timing accuracy to be within 200 ps. To meet the requirement, the designed SDRAM adopts a digitally self-calibrated on-die-termination with linearity error of /spl plusmn/1% and achieves over 1.2 Gbps/pin stable operation by(More)
