A MASS STORAGE DEVICE HAVING BOTH XIP FUNCTION AND STORAGE FUNCTION

摘要

A mass storage device for mobile phone having both XIP function and storage function is disclosed. The mass storage device having both XIP function and storage function comprises a NAND flash memory divided into an XIP (execute-in-place) area for storing a program code and a storage area for storing a mass data; and a controller for controlling the XIP area in such a manner that a host can be accessible to the XIP area through a NOR interface port at the request of an arbitrary access from the host and performing a storage interface function in such a manner that the host can be accessible to the storage area in a block unit through a storage interface port at the access request of a block unit from the host.
