1. tWCS, tRWD, tCWD, and tAWD are not restrictive parameters. They are included in the datasheet as electrical characteristics only. If  
WCS tWCS(min.), the entire cycle is an early write cycle and the data pin will remain open circuit (high impedance) through the  
t
entire cycle. If tRWD tRWD(min.), tCWD tCWD(min.), and tAWD tAWD(min.), the cycle is a Read-Modify-Write cycle and the data will  
contain read from the selected cell: If neither of the above sets of conditions is met, the condition of the data (at access time) is  
indeterminate.
