Write cycles may be byte write cycles (either LCAS or UCAS active).  
Read cycles may be byte read cycles (either LCAS or UCAS active).  
One CAS must be active (either LCAS or UCAS).

and I  
depend on output loading. Specified values are obtained with the output open.

CC4  
An initial pause of 200 µs is required after power-up followed by any 8 RAS cycles before proper device operation is achieved. In the case of an internal  
refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 8 initialization cycles are required after  
extended periods of bias without clocks (greater than 8 ms).

AC Characteristics assume t = 2 ns. All AC parameters are measured with a load as described in AC test conditions below.
