Notes concerning CAS1 and CAS2 control

Overlap the active-low timings of CAS1 and CAS2. Skew between CAS1 and CAS2 is allowed

under the following conditions:

(1) The timing specification for CAS1 and CAS2 should be met individually.

(2) Different operation modes for CAS1/CAS2 are not allowed (as shown below).

RAS

CAS1

Delayed write

CAS2

Early write

WE

(3) Closely separated CAS1/CAS2 control is not allowed. However, when the condition

(tCP ≤ tUL) is satisfied, fast page mode can be performed.
