DSC-4845/8 709379/69L High-Speed 32/16K x 18 Synchronous Pipelined Dual-Port Static RAM Description The IDT709379/69 is a high-speed 32/16K x 18 bit synchronous Dual-Port 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. Industrial and Commercial Temperature Ranges With an input data register, the IDT709379/69 has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using CMOS high-performance technology, these devices typically operate on only 1.2W of power.

Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 2. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge. 3. ADS = VIL and CNTRST = VIH. 4. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, UB = VIH, or LB = VIH following the next rising edge of the clock. Refer to Truth Table 1. 5. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 6. If UB or LB was HIGH, then the Upper Byte and/or Lower Byte of DATAOUT for Qn + 2 would be disabled (High-Impedance state). 7. "X" here denotes Left or Right port.

B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT709379/69 for this waveform, and are setup for depth expansion in this example. ADDRESS(B1) = ADDRESS(B2) in this situation. 2. UB, LB, OE, and ADS = VIL; CE1(B1), CE1(B2), R/W and CNTRST = VIH. 3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 4. CE0, UB, LB, and ADS = VIL; CE1 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". 9 6.42 709379/69L High-Speed 32/16K x 18 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges Timing Waveform of Pipelined Read-to-Write-to-Read (OE = VIL)(3) tCYC2 tCH2 tCL2 CLK CE0 tSC tHC tSB tHB CE1 UB, LB tSW tHW R/W (4) ADDRESS tSW tHW An tSA tHA An +1 An + 2 An + 3 An + 2 An + 4 tSD tHD DATAIN Dn + 2 tCD2 (2) tCKHZ (1) (1) tCKLZ tCD2 Qn + 3 Qn DATAOUT (5) READ NOP WRITE READ 4845 drw 11 Timing Waveforn of Pipelined Read-to-Write-to-Read (OE Controlled)(3) tCH2 tCYC2 tCL2 CLK CE0 tSC tHC tSB tHB CE1 UB, LB tSW tHW R/W (4) ADDRESS tSW tHW An tSA tHA An +1 An + 2 tSD DATAIN An + 4 An + 5 tHD Dn + 2 tCD2 (2) An + 3 Dn + 3 tCKLZ(1) tCD2 Qn DATAOUT Qn + 4 tOHZ(1) OE READ WRITE READ 4845 drw 12 NOTES: 1.

CE0, UB, LB = VIL; CE1 = VIH. 3. The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH. 4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals. 6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. 7. CNTEN = VIL advances Internal Address from ‘An’ to ‘An +1’. The transition shown indicates the time required for the counter to advance. The ‘An +1’ Address is written to during this cycle. 13 6.42 709379/69L High-Speed 32/16K x 18 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges A Functional Description Depth and Width Expansion The IDT709379/69 provides a true synchronous Dual-Port Static RAM interface. Registered inputs provide minimal set-up and hold times on address, data, and all critical control inputs. All internal registers are clocked on the rising edge of the clock signal, however, the self-timed internal write pulse is independent of the LOW to HIGH transition of the clock signal. An asynchronous output enable is provided to ease asynchronous bus interfacing. Counter enable inputs are also provided to stall the operation of the address counters for fast interleaved memory applications. CE0 = VIH or CE1 = VIL for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT709379/69's for depth expansion configurations. When the Pipelined output mode is enabled, two cycles are required with CE0 = VIL and CE1 = VIH to reactivate the outputs. The IDT709379/69 features dual chip enables (refer to Truth Table I) in order to facilitate rapid and simple depth expansion with no requirements for external logic. Figure 4 illustrates how to control the various chip enables in order to expand two devices in depth. The IDT709379/69 can also be used in applications requiring expanded width, as indicated in Figure 4. Since the banks are allocated at the discretion of the user, the external controller can be set up to drive the input signals for the various devices as required to allow for 36-bit or wider applications.
