19.When output buffers are enabled once, sustain the low impedance state until valid data is
obtained. When output buffer is turned on and off within a very short time, generally it causes
large V

20.t
(min) can be achieved during a series of EDO page mode write cycles or EDO page mode
read cycles. If both write and read operation are mixed in a EDO page mode
RAS
cycle (EDO
page mode mix cycle (1), (2)), minimum value of
CAS
cycle (t
+ t
+ 2 t
) becomes greater
than the specified t
(min) value. The value of
CAS
cycle time of mixed EDO page mode is
shown in EDO page mode mix cycle (1) and (2).
21.Data output turns off and becomes high impedance from later rising edge of
RAS

Hold time and turn off time are specified by the timing specifications of later rising edge of
