SDRAM Bus Signal Timing
1. Timing parameters assume that the system uses a zero delay clock buffer for SDCLK before it is distributed to SDRAM.
2. Capacitive loading effects on signal lines are shown in

SDRAM parts will deliver. Increased performance on the SDRAM bus occurs because the data pins only drive one load.
