Revision A5
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 1.
Table 1. Address Sequence of Sequential Mode

BL = 2 (disturb address is A0)
Data 1
n + 1
No address carry from A0 to A1
Data 2
n + 2
BL = 4 (disturb addresses are A0 and A1)
Data 3
n + 3
No address carry from A1 to A2
Data 4
n + 4
Data 5
n + 5
BL = 8 (disturb addresses are A0, A1 and A2)
Data 6
n + 6
No address carry from A2 to A3
Data 7
n + 7
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 2.
