Notes
1. t
WCS
, t
RWD
, t
CWD
, and t
AWD
are not restrictive parameters. They are included in the data sheet as electrical characteristics only. If
t
WCS
≥
t
WCS
(min.), the entire cycle is an early write cycle and the data pin will remain open circuit (high impedance) through the
entire cycle; If t
RWD
≥
t
RWD
(min.), t
CWD
≥
t
CWD
(min.) and t
AWD
≥
t
AWD
(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 are met, the condition of the data (at access time) is
indeterminate.
2. Data-in set-up and hold is measured from the latter of the two timings, CAS or WE.
