Extended Mode Register
The Extended Mode Register controls functions beyond those controlled by the Mode Register; these
additional functions include DLL enable/disable, bit A0; output drive strength selection, bit A1; and
QFC output enable/disable, bit A2 (NTC optional). These functions are controlled via the bit settings
shown in the Extended Mode Register Definition. The Extended Mode Register is programmed via the
Mode Register Set command (with BA0 = 1 and BA1 = 0) and retains the stored information until it is
programmed again or the device loses power. The Extended Mode Register must be loaded when all
banks are idle, and the controller must wait the specified time before initiating any subsequent
operation. Violating either of these requirements result in unspecified operation.
