DLL Enable / Disable
The DLL must be enabled for normal operation. DLL enable is required during power-up initialization, and upon returning to
normal operation after having disabled the DLL for the purpose of debug or evaluation (upon exiting Self Refresh Mode, the
DLL is enabled automatically). Any time the DLL is enabled, 200 clock cycles must occur before a READ command can be
issued.
Output Drive Strength
The device support full drive strength and reduced drive strength options, intended for lighter load and/or point-to-point
environments.
