NOTES:
3603 tbl 14b
1. Port-to-port delay through RAM cells from writing port to reading port, refer to "Timing Waveform of Write with Port-to-Port Read and BUSY (M/ S = V IH )".
2. To ensure that the earlier of the two ports wins.
3. t BDD is a calculated parameter and is the greater of 0, t WDD – t WP (actual), or t DDD – t DW (actual).
4. To ensure that the write cycle is inhibited on port "B" during contention on port "A".
5. To ensure that a write cycle is completed on port "B" after contention on port "A".
6. 'X' in part numbers indicates power rating (S or L).
