9 / 13 page  6.05 9 IDT71342SA/LA HIGH-SPEED 4K x 8 DUAL-PORT STATIC RAM WITH SEMAPHORE COMMERCIAL TEMPERATURE RANGE TIMING WAVEFORM OF SEMAPHORE READ AFTER WRITE TIMING, EITHER SIDE(1) NOTES: 1. CE = VIH for the duration of the above timing (both write and read cycle). 2. "DATAOUT VALID" represents all I/O's (I/O0-I/O7) equal to the semaphore value. NOTES: 1. D0R = D0L = VIL, CER = CEL = VIH, Semaphore Flag is released from both sides (reads as ones from both sides) at cycle start. 2. All timing is the same for left and right ports. Port "A" may be either left or right port. Port "B" is the opposite from port "A". 3. This parameter is measured from the point where R/ W "A" or SEM "A" goes High until R/W "B" or SEM "B" goes High. 4. If tSPS is not satisfied, there is no guarantee which side will be granted the semaphore flag. A0"A" - A2"A" tSPS R/ W "A" SEM "A" "A" SIDE (2) A0"B" - A2"B" R/ W "B" SEM "B" "B" SIDE MATCH MATCH 2721 drw 13 (2) TIMING WAVEFORM OF SEMAPHORE CONTENTION(1, 3, 4) A0 - A2 VALID ADDRESS VALID ADDRESS DATAIN VALID DATAOUT VALID SEM R/ W OE DATA0 tAW tEW tWR tDW tDH tWP tAS tSWRD tSOP tAOE tACE tSAA tOH Test Cycle (Read Cycle) Write Cycle 2721 drw 12 (2) |
