DATA STORAGE DEVICE AND DATA PROCESSING SYSTEM INCLUDING THESAME

摘要

The present invention relates to a data storage device, and more specifically to a data storage device capable of preventing exposure of security data and a data processing system including the same. The data processing system comprises: a host device; and a data storage device made up to store data accessed by the host device. The data storage device comprises: a non-volatile memory device having memory cells; and a controller made up to control the non-volatile memory device. The controller is made up to control the non-volatile memory device for a target memory cell, in which data requested for deleting is stored, to be programmed when data deleting is requested from the host device.
