• Manufacturer Part Number: IDT7024L
• Description: HIGH-SPEED 4K x 16 DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

IDT7024S/L
HIGH-SPEED 4K x 16 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 Read With
2. To ensure that the earlier of the two ports wins.
3. tBDD is a calculated parameter and is the greater of 0ns, 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 numbers indicates power rating (S or L).
