Read/Write Timing
Notes:
*1. Q(A4) refers to output from address A4. Q(A4+1) refers to output from the internal burst address immediately
following A4.
*2. Timing for
CE2
and CE2 is identical to that for
CE
. As shown in this diagram, when
CE
is LOW,
CE2
is
LOW and CE2 is HIGH. When
CE
is HIGH,
CE2
is HIGH and CE2 is LOW.
*3. Byte Write enables are decided by means of a Write truth table.
*4. Pass-through occurs when data is first written, then Read in sequence.
