*1 : Maximum value is applicable if CE1 is kept at Low without change of address input.
*2 : Address should not be changed within a minimum tRC.
*3 : The output load 50 pF with 50 Ω termination to VDD × 0.5 V.
*4 : The output load 5 pF without any other load.
*5 : Applicable when CE1 is kept at Low.
*6 : tVPL is specified from the falling edge of either CE1 or ADV whichever comes late. The sum of actual tVPL and
tASVL (or tASC) must be equal or greater than the specified minimum value of tVPL.
*7 : Applicable to address access when at least two of address inputs are switched from the previous state.
*8 : tRC (Min) must be satisfied.
*9 : Applicable to Write to Read sequence controlled by WE and OE, Read operation is initiated after tWHOL (Min)
from the rising edge of WE therefore tAA is specified after tWHOL (Min) .
