NOTES:
2942 tbl 13b
1. Port-to-port delay through SRAM cells from writing port to reading port, refer to "Timing Waveform of Read With BUSY (M/ S = V IH ) or "Timing Waveform of Write With
Port-To-Port Delay (M/ S =V IL )".
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 during contention.
5. To ensure that a write cycle is completed after contention.
6. "X" is part numbers indicates power rating (S or L).
