WE# is high for read cycle. 2. Device is continuously selected OE# = low, CE# = low. 3. Address must be valid prior to or coincident with CE# = low,; otherwise tAA is the limiting parameter. 4.tCLZ, tOLZ, tCHZ and tOHZ are specified with CL = 5pF . Transition is measured ±500mV from steady state. 5.At any gi ven te mperature and voltage condition, tCHZ is less than tCLZ , tOHZ is less than tOLZ. AUG09 v1.4 Alliance Memory Inc Page 5 of 14

WE#, CE# must be high during all address transitions. 2. A write occurs during the overlap of a low CE#, low WE#. 3. During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be placed on the bus. 4. During this period, I/O pins are in the output state, and input signals must not be applied. 5. If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state. 6. tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state. AUG09 v1.4 Alliance Memory Inc Page 6 of 14
