STORAGE APPARATUS INCLUDING DEVICE CONTROLLER, THE DEVICE CONTROLLER FOR PERFORMING ADDRESS MAPPING METHOD

摘要

The present invention relates to an address mapping method conducted by a drive controller and, more specifically, to an address mapping method configured to store data in a flash memory in order to allow the data to have a continuous physical address depending on a data property, based on a data logic address, wherein the data is configured to state mapping units, each of which has the different size from each other. According to the present invention, the address mapping method may manage data through mapping units which are different from each other, depending on data storing areas by recognizing a workload property.
