.
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.
.
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.
