Pin Descriptions—512K × 18
Partial Truth Table for Read/Write
Interleaved Burst Address Table
(MODE = V
Notes:
Read
No Write
Write Byte a (DQa)
Write Byte b (DQb)
Write Byte c (DQc)
Write Byte d (DQd}
Write all bytes
2. L means logic LOW. H means logic HIGH. X means Don’t Care.
3. Multiple bytes may be selected during the same cycle.
4. BWc and BWd apply to 256K × 36 device only.
5. Upon completion of the Burst sequence, the counter wraps around to its initial state and continues counting.
