• Manufacturer: Integrated Device Technology

IDT7006S/L
HIGH-SPEED 16K x 8 DUAL-PORT STATIC RAM
AC ELECTRICAL CHARACTERISTICS OVER THE
OPERATING TEMPERATURE AND SUPPLY VOLTAGE RANGE
NOTES:
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
2. To ensure that the earlier of the two ports wins.
3. t
4. To ensure that the write cycle is inhibited with port "B" during contention on port "A".
5. To ensure that a write cycle is completed on port "B" after contention with port "A".
6. "X" is part numbers indicates power rating (S or L).
