BA1 = 0) and will retain the stored information until it
is programmed again or the device loses power. The
enabling of the DLL should always be followed by a
LOAD MODE REGISTER command to the mode regis-
ter (BA0/ BA1 both LOW) to reset the DLL.
all device banks are idle and no bursts are in progress,
and the controller must wait the specified time before
initiating any subsequent operation. Violating either of
these requirements could result in unspecified opera-
tion.
DLL Enable/Disable
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 evalua-
tion. (When the device exits self refresh mode, the DLL
is enabled automatically.) Any time the DLL is enabled,
a DLL Reset and 200 clock cycles with CKE high must
occur before a READ command can be issued.
