10 / 11 page IDT7134SA/LA High-Speed 4K x 8 Dual-Port Static SRAM Military, Industrial and Commercial Temperature Ranges 10 Truth Table I Read/Write Control Functional Description The IDT7134 provides two ports with separate control, address, and I/O pins that permit independent access for reads or writes to any location in memory. These devices have an automatic power down featurecontrolledbyCE.TheCEcontrolson-chippowerdowncircuitry that permits the respective port to go into standby mode when not selected (CE HIGH). When a port is enabled, access to the entire memory array is permitted. Each port has its own Output Enable control(OE).Inthereadmode,theports OEturnsontheoutputdrivers whensetLOW.Non-contentionREAD/WRITEconditionsareillustrated in the table below. Timing Waveform of Write Cycle No. 2, CE Controlled Timing(1,4) NOTES: 1. R/W or CE must be HIGH during all address transitions. 2. A write occurs during the overlap (tEW or tWP) of a CE =VIL and R/W = VIL. 3. tWR is measured from the earlier of CE or R/W going HIGH to the end-of-write cycle. 4. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the High-impedance state. 5. Timing depends on which enable signal (CE or R/W) is asserted last. NOTE: 1. A0L - A11L ≠ A0R - A11R "H" = VIH, "L" = VIL, "X" = Dont Care, and "Z" = High Impedance Left or Right Port(1) R/W CE OE D0-7 Function X H X Z Port Deselected and in Power-Down Mode, ISB2 or ISB4 XH X Z CER = CEL = H, Power Down Mode ISB1 or ISB3 LL X DATAIN Data on port written into memory HL L DATAOUT Data in memory output on port X X H Z High impedance outputs 2720 tbl 11 2720 drw 12 R/ W tWC ADDRESS DATAIN CE tDW tWR (3) tDH tEW (2) tAW tAS (5) |
