Mode Register
Notes:
The mode register 1 (MR1) controls additional functions and features not available in
the other mode registers: Q OFF (OUTPUT DISABLE), TDQS (for the x8 configuration
only), DLL ENABLE/DLL DISABLE, R
CAS ADDITIVE latency, and OUTPUT DRIVE STRENGTH. These functions are
controlled via the bits shown in Figure 56. The MR1 register is programmed via the MRS
command and retains the stored information until it is reprogrammed, until RESET#
goes LOW, or until the device loses power. Reprogramming the MR1 register will not
alter the contents of the memory array, provided it is performed correctly.
The MR1 register must be loaded when all banks are idle and no bursts are in progress.
The controller must satisfy the specified timing parameters
initiating a subsequent operation.
1. MR1[16, 13, 10, 8] are reserved for future use and must be programmed to “0.”
2. During write leveling, if MR1[7] and MR1[12] are “1” then all R
3. During write leveling, if MR1[7] is a “1,” but MR1[12] is a “0,” then only R
The DLL may be enabled or disabled by programming MR1[0] during the LOAD MODE
command, as shown in Figure 56. The DLL must be enabled for normal operation. DLL
enable is required during power-up initialization and upon returning to normal opera-
tion after having disabled the DLL for the purpose of debugging or evaluation. Enabling
the DLL should always be followed by resetting the DLL using the appropriate LOAD
MODE command.
If the DLL is enabled prior to entering self refresh mode, the DLL is automatically
disabled when entering SELF REFRESH operation and is automatically reenabled and
reset upon exit of SELF REFRESH operation. If the DLL is disabled prior to entering self
refresh mode, the DLL remains disabled even upon exit of SELF REFRESH operation
until it is reenabled and reset.
