• Manufacturer Part Number: IDT70V3389S
• Description: High-speed 3.3v 64k X 18 Synchronous Pipelined Dual-port Static Ram With 3.3v Or 2.5v Interface
• Manufacturer: Integrated Device Technology

RAM. The memory array utilizes Dual-Port memory cells to allow
simultaneous access of any address from both ports. Registers on control,
data, and address inputs provide minimal setup and hold times. The timing
latitude provided by this approach allows systems to be designed with very
short cycle times. With an input data register, the IDT70V3389 has been
optimized for applications having unidirectional or bidirectional data flow
