HF88M04
access time in this way is specified as t
AA
. In this device, the Address Access Time decrease
monotonically with increasing voltage, and it is shorter than Chip Enable Access Time when the
Operation Voltage is higher then 4.5 V. Therefore in V
op
higher than 4.5 Volts, it is more advisable to use
the Address Access Mode to achieve faster access to ROM data when the power consumption is not a
concern.
