IDT7016S/L
High-Speed 16K x 9 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Timing Waveform of Read with BUSY
(2,4,5)
t WC
(M/ S = V IH )
ADDR "A"
MATCH
t WP
R/ W "A"
DATA IN "A"
t APS (1)
t DW
VALID
t DH
ADDR "B"
MATCH
BUSY "B"
t WDD
DATA OUT "B"
t DDD (3)
NOTES:
1. To ensure that the earlier of the two ports wins. t APS is ignored for M/ S =V IL .
2. CE L = CE R = V IL .
3. OE = V IL for the reading port.
4. If M/ S =V IL (SLAVE), BUSY is an input. Then for this example BUSY “A” = V IH and BUSY “B” input is shown above.
5. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from Port "A".
Timing Waveform of Write with BUSY (3)

3190 drw 14
NOTES:
1. t WH must be met for both BUSY input (SLAVE) and output (MASTER).
2. BUSY is asserted on port "B" blocking R/ W "B" , until BUSY "B" goes HIGH.
3. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from Port "A".
