IDT70T3509M Integrated Device Technology, IDT70T3509M Datasheet - Page 14

• Manufacturer Part Number: IDT70T3509M
• Description: High-speed 2.5v 1024k X 36 Synchronous Dual-port Static Ram With 3.3v Or 2.5v Interface
• Manufacturer: Integrated Device Technology

Timing Waveform of Flow-Through Read-to-Write-to-Read (OE = V
NOTES:
1. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
2. CE
3. Addresses do not have to be accessed sequentially since ADS = V
4. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.
