EXTENDED MODE REGISTER

DLL disable / enable mode can be programmed in the extended

mode register (EMRS). The extended mode register stores these

data until the next EMRS command, which may be issued when all

banks are in idle state. After tMRD from a EMRS command, the DDR

SDRAM is ready to accept the new command.
