IDT70V05 Integrated Device Technology, IDT70V05 Datasheet - Page 13

• Manufacturer Part Number: IDT70V05
• Description: High-speed 3.3v 8k X 8 Dual-port Static Ram
• Manufacturer: Integrated Device Technology

AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage Range
NOTES:
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
2. To ensure that the earlier of the two ports wins.
3. t
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 number indicates power rating (S or L).
