1. tWCS, tRWD, tCWD, tAWD, and tCPW are not restrictive parameters. They are included in the data sheet as electrical characteristics  
only. If tWCS tWCS(min.), the entire cycle is an early write cycle and the data pin will remain open circuit (high impedance) through  
the entire cycle; If tRWD tRWD(min.), tCWD tCWD(min.), tAWD tAWD(min.) and tCPW tCPW(min.)(Fast Page Mode), 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 are met, the  
condition of the data (at access time) is indeterminate.
