Notes:
13. This part has a voltage regulator internally; tPOWER is the time that the power needs to be supplied above VDD minimum initially before a Read or Write operation
can be initiated.
14. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
15. At any given voltage and temperature, tOEHZ is less than tOELZ and tCHZ is less than tCLZ to eliminate bus contention between SRAMs when sharing the same
data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed
to achieve Three-state prior to Low-Z under the same system conditions
16. This parameter is sampled and not 100% tested.
17. Timing reference level is 1.5V when VDDQ = 3.3V and is 1.25V when VDDQ = 2.5V.
18. Test conditions shown in (a) of AC Test Loads unless otherwise noted.
