Abstract: A non-volatile memory (NVM) apparatus and an address classification method thereof are provided. The NVM apparatus includes a NVM and a controller. The controller accesses the NVM in accordance with a write command of a host. The controller may perform the address classification method. The address classification method includes: providing a data look-up table, wherein the data look-up table includes a plurality of data entries, each of the data entries includes a logical address information, a counter value and a timer value; searching the data look-up table based on the logical address of the write command in order to obtain a corresponding counter value and a corresponding timer value; and determining whether the logical address of the write command is a hot data address based on the corresponding counter value and the corresponding timer value.
