• Manufacturer Part Number: IDT70261S
• Description: High-speed 16k X 16 Dual-port Static Ram With Interrupt
• Manufacturer: Integrated Device Technology

NOTES:
1. To ensure that the earlier of the two ports wins. t
2. CE
3. OE = V
4. If M/S = V
5. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from port "A".
NOTES:
1. t
2. BUSY is asserted on port "B" blocking R/W
