Activating a Specific Row in a Specific Bank
The ACTIVE command is used to open (or activate) a row in a particular bank for a
subsequent access, like a read or a write, as shown in Figure 15. The value on the BA0,
BA1 inputs selects the bank, and the address provided on inputs A0–An selects the row.
The READ command is used to initiate a burst read access to an active row, as shown in
Figure 16 on page 40. The value on the BA0, BA1 inputs selects the bank, and the address
provided on inputs A0–Ai (where Ai is the most significant column address bit for a given
density and configuration, see Table 2 on page 2) selects the starting column location.
