Read and Write Timing
Remarks 1. Q00 refers to output from address A0+0.
2. Outputs are disabled (high impedance) 2.5 clock cycles after the last READ (R# = LOW) is input in the
3. In this example, if address A0 = A1, data Q00 = D10, Q01 = D11.

Data in
Q01 refers to output from the next internal burst address following A0,i.e.,A0+1.
sequences of [READ/WRITE]-[NOP/WRITE], [READ/WRITE]-[NOP/NOP], [READ/NOP]-[NOP/WRITE]
and [READ/NOP] -[NOP/NOP].
Write data is forwarded immediately as read results.
