The table of timing values shows either a minimum or a maximum limit for each parameter. Input requirements are specified from the external system point of view. For example, address setup time would be shown as a minimum since the system must supply at least that much time (even though most devices do not require it). On the other hand, responses from the memory are specified from the device point of view. For example, the access time would be shown as a maximum since the device never provides data later than that time. 6.5.2 Waveforms.
