Notes:

1. Dual Output data

DQ0 = (D6, D4, D2, D0)

DQ1 = (D7, D5, D3, D1)

2. Dual Input Address

DQ0 = A22, A20, A18, A16, A14, A12, A10, A8 ; A6, A4, A2, A0, dummy 6, dummy 4, dummy 2, dummy 0

DQ1 = A23, A21, A19, A17, A15, A13, A11, A9 ; A7, A5, A3, A1, dummy 7, dummy 5, dummy 3, dummy 1

3. Quad Data

DQ0 = (D4, D0, â¦â¦ )

DQ1 = (D5, D1, â¦â¦ )

DQ2 = (D6, D2, â¦... )

DQ3 = (D7, D3, â¦... )

4. Quad Input Address

DQ0 = A20, A16, A12, A8, A4, A0, dummy 4, dummy 0

DQ1 = A21, A17, A13, A9, A5, A1, dummy 5, dummy 1

DQ2 = A22, A18, A14, A10, A6, A2, dummy 6, dummy 2

DQ3 = A23, A19, A15, A11, A7, A3, dummy 7, dummy 3

5. Quad I/O Fast Read Data

DQ0 = ( dummy 12, dummy 8, dummy 4, dummy 0, D4, D0 )

DQ1 = ( dummy 13, dummy 9, dummy 5, dummy 1, D5, D1 )

DQ2 = ( dummy 14, dummy 10, dummy 6, dummy 2, D6, D2 )

DQ3 = ( dummy 15, dummy 11, dummy 7, dummy 3, D7, D3 )

00-7FH, 80-FFH

00-FFH

If input data is not between 00h~05h or user does not Set Burst, the Burst length will be 8 Bytes in

default.

7. Two dummy cycles (4 clocks) are necessary for Read Burst with Wrap mode.

8. Three dummy cycles (6 clocks) are necessary for Fast Read Burst with Wrap mode.
