IDT70V3379S Integrated Device Technology, IDT70V3379S Datasheet - Page 6

• Manufacturer Part Number: IDT70V3379S
• Description: High-speed 3.3v 32k X 18 Synchronous Pipelined Dual-port Static Ram With 3.3v Or 2.5v Interface
• Manufacturer: Integrated Device Technology

NOTES:
1. "H" = V
2. Read and write operations are controlled by the appropriate setting of R/W, CE
3. Outputs are in Pipelined mode: the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other memory control signals including CE
5. The address counter advances if CNTEN = V
