WE is high for read cycle. 2. All read cycle timing is referenced from the last valid address to the first transition address. 3. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit condition and are not referenced to VOH or VOL levels. 4. At any given temperature and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from device to device. 5. Transition is measured 200mV from steady state voltage with Load(B). This parameter is sampled and not 100% tested. 6. Device is continuously selected with CS=VIL. 7. Address valid prior to coincident with CS transition low. 8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle. -6- Rev 2.2 May 1999 PRELIMINARY CMOS SRAM K6R4008V1B-C/B-L, K6R4008V1B-I/B-P TIMING WAVEFORM OF WRITE CYCLE(1) (OE= Clock) tWC Address tWR(5) tAW OE tCW(3) CS tWP(2) tAS(4) WE tDW Data in High-Z tDH Valid Data tOHZ(6) High-Z(8) Data out TIMING WAVEFORM OF WRITE CYCLE(2) (OE=Low Fixed) tWC Address tWR(5) tAW tCW(3) CS tAS(4) tWP1(2) WE tDW Data in High-Z tDH Valid Data tWHZ(6) tOW (10) (9) High-Z(8) Data out TIMING WAVEFORM OF WRITE CYCLE(3) (CS = Controlled) tWC Address tAW tWR(5) tCW(3) CS tAS(4) tWP(2) WE tDW Data in High-Z Valid Data tLZ Data out tDH High-Z tWHZ(6) High-Z(8) High-Z -7- Rev 2.2 May 1999 PRELIMINARY CMOS SRAM K6R4008V1B-C/B-L, K6R4008V1B-I/B-P NOTES(WRITE CYCLE) 1. All write cycle timing is referenced from the last valid address to the first transition address. 2. A write occurs during the overlap of a low CS and WE. A write begins at the latest transition CS going low and WE going low ; A write ends at the earliest transition CS going high or WE going high. tWP is measured from the beginning of write to the end of write. 3. tCW is measured from the later of CS going low to end of write. 4. tAS is measured from the address valid to the beginning of write. 5. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS or WE going high. 6. If OE, CS and WE are in the Read Mode during this period, the I/O pins are in the output low-Z state. Inputs of opposite phase of the output must not be applied because bus contention can occur. 7. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle. 8. If CS goes low simultaneously with WE going or after WE going low, the outputs remain high impedance state. 9. Dout is the read data of the new address. 10. When CS is low : I/O pins are in the output state. The input signals in the opposite phase leading to the output should not be applied.
