Extended Mode Register fields
(E-1) DLL Switch field (A0)
(E-2) Output Driver Impedance Control field (A1 to A4)
(E-3) Strobe Select (A6 / A5)
(E-4) Reserved field (A7 to A14)
(1)
(2)
This bit is used to enable DLL. When the A0 bit is set “0”, DLL is enabled. This bit must be set to “0” for
normal operation.
This field is used to choose Output Driver Strength. Three types of Driver Strength are supported.
QS and DQ Driver Strength can be chosen separately. A2-A1 specified the DQ Driver Strength. A4-A3
specified the QS Driver Strength.
Two types of data strobe are supported. This field is used to choose the type of data strobe.
These bits are reserved for future operations and must be set to “0” for normal operation.
Unidirectional DS/QS mode
Data strobe is separated DS for write strobe and QS for read strobe.
DS is used to sample write data at write operation. QS is aligned with read data at Read operation.
Unidirectional DS/Free running QS mode
Data strobe is separated DS for write strobe and QS for read strobe.
DS is used to sample write data at write operation. QS is aligned with read data and always
clocking.
