IDT70T3589 Integrated Device Technology, IDT70T3589 Datasheet - Page 13

• Manufacturer Part Number: IDT70T3589
• Description: 64k X 36 Sync, 3.3v/2.5v Dual-port Ram, Interleaved I/o S
• Manufacturer: Integrated Device Technology

Timing Waveform of Read Cycle for Pipelined Operation
(FT/PIPE
NOTES:
1. OE is asynchronously controlled; all other inputs depicted in the above waveforms are synchronous to the rising clock edge.
2. ADS = V
3. The output is disabled (High-Impedance state) by CE
4. Addresses do not have to be accessed sequentially since ADS = V
5. If BE
6. "x" denotes Left or Right port. The diagram is with respect to that port.
