the data becomes available at the data bus, and the processor needs some time to read it. So
the CAS should remain active until the processor reads it. If CAS is inactivated, the output
buff ers are disabled, and the data is no longer available at the output. However, only after
the CAS signal goes high, can a new cycle start.  us, delaying the inactivation of the CAS
