NOTES:
1. Port-to-port delay through RAM cells from writing port to reading port, refer to "Timing Waveform of Write Port-to-Port Read and BUSY (M/S = V
2. To ensure that the earlier of the two ports wins.
3. t
4. To ensure that the write cycle is inhibited on Port "B" during contention with Port "A".
5. To ensure that a write cycle is completed on Port "B" after contention with Port "A".
6. 'X' in part number indicates power rating (S or L).
