Abstract
A data management device and a data management method for a flash memory, in which physical addresses are classified according to pages, each of which is a physical data operation unit, and a predetermined data operation is performed with respect to the classified physical addresses. The data management device and method reduce time required for the data operation in a large-block flash memory, in which a physical data operation unit is larger than a logical data operation unit. As a result, an optimal data operation can be achieved in a large-block flash memory.
