9 / 15 page  6.42 IDT709189L High-Speed 64K x 9 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges 9 Timing Waveform of Write with Port-to-Port Flow-Through Read(4,5,7) NOTES: 1. B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT709189 for this waveform, and are setup for depth expansion in this example. ADDRESS(B1) = ADDRESS(B2) in this situation. 2. OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH. 3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 4. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. 5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to. 6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD. If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case. 7. All timing is the same for both Left and Right ports. Port "A" may be either Left or Right port. Port "B" is the opposite from Port "A".
