Mode Register Set A19 ~ A5 A4 A3 A2 A1 A0 0 ZZ Enable/Disable Array On/Off on /ZZ Half Selection Array Refresh Area /ZZ Enable/Disable A4 Type 0 Deep Power Down Enable 1 DPD Disable (Default) Array On/Off on /ZZ A3 Type 0 Partial Array Refresh Mode (Default) 1 Reduced Memory Size Mode Note: If the register is written to enable the Deep Power Down, the part will go into Deep Power Down during the following time that /ZZ is driven low and there is no MRS update. When /ZZ is driven high, all of the register settings will return to default state for the part (i.e. full array refresh, Deep Power Down Disabled). Note: The RMS(Reduced Memory Size) mode is enabled after /ZZ goes high and remains enabled after /ZZ goes high. To change to a different mode, the mode register will have to be rewritten.
