7.12 Addressing Sequence of Sequential Mode
A column access is performed by increasing the address from the column address which is input to
the device. The disturb address is varied by the Burst Length as shown in Table 2.

7.13 Addressing Sequence of Interleave Mode
A column access is started in the input column address and is performed by inverting the address bit
in the sequence shown in Table 3.
