1. tWCS, tRWD, tCWD and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics
only. If tWCS ≥ tWCS (min), the 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) and tAWD ≥ tAWD (min), the cycle is a Read-Modify-Write cycle and the data out
will contain data read from the selected cell. If neither of the above sets of conditions are satisfied, the condition of the data out (at
access time) is indeterminate.
2. Either tCDD or tOED must be satisfied.
3. These parameters are referenced to CAS leading edge in early write cycles and to WE leading edge in Read-Modify-Write cycles.
