Notes: 1. DM must be driven low all the time. DQS, /DQS are used according to write commands, otherwise MID-LEVEL.
2. Burst sequence driven on each DQ signal by write command. Outside burst operation, DQ signals are MID-LEVEL.
3. BA: BA0 to BA2.
4. Am: m means Most Significant Bit (MSB) of Row address.
