TIMING LIMITS

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. Thus, ad-

dress setup time is 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. Thus, the access time is shown as a maximum since

the device never provides data later than that time.
