There are two ways of accessing the ROM data. The first one is to assert the valid address on the Address
Bus, then assert CEn “low” to enable the ROM array. The access time in this mode is specified as tACE
.
The advantage of this access mode is that power consumption can be lowered. The second access mode
keeps the CEn “low” while changes the addresses to access the contents of ROM data. The access time in
this way is specified as tAA.
