Flash memory access time

Does anybody know why flash memory read and write access time increases as the size of the flash memory gets larger? And suppose you are given the data transfer rate and controller transfer rate, how do you compute the minimum access time of flash memory? Thanks

The access time has nothing to do with the transfer rate of the data itself. It’s just a specification of the used components. A component can have an access time of 60nanoseconds for instance.
