SYSTEMS AND METHODS FOR ACCESSING A DATA STORAGE DEVICE

摘要

Systems and methods are disclosed for efficiently accessing memory locations within the memory space of a data storage device. In one aspect, the invention is understood as a memory driver that accesses the memory space of a PC memory device. In one embodiment, the memory driver of the invention opens a window in the memory space of a PC-Card memory device. Each time an operating system issues a read or write memory request to the memory driver, the memory driver generates a set of commands to issue to the memory card that direct the memory card to position the window over that portion of the memory card's memory space that contains the memory locations which the operating system is attempting to read from or write to. Consequently, a memory driver according to the invention continuously modifies an open window within the memory space of the PC-Card memory to service the read/write requests of the operating system.
