DQM
1. There are 4 DQMi(i=0~3).
Each DQMi masks 8 DQi's.(1 Byte, 1 Pixel for 8 bpp)
2. DQM makes data out Hi-Z after 2 clocks which should masked by CKE " L".

2. DQM Operation
1) Write Mask (BL=4)
2) Read Mask (BL=4)
*Note :
DQM to Data-in Mask = 0CLK
DQM to Data-out Mask = 2CLK
3) DQM with Clock Suspended (Full Page Read)
