Title:
SYSTEM AND METHOD OF HOST REQUEST MAPPING
Document Type and Number:
WIPO Patent Application WO/2010/093487
Kind Code:
A3
Abstract:
Systems and methods for reading data are disclosed. In a particular embodiment, a data storage device includes a host interface that is adapted to couple the data storage device to a host. The host includes memory that is addressable by a host memory address space. The data storage device also includes a device address space that is independent from the host memory address space. The device address space includes a first address region and a second address region, where the second address region is distinct from the first address region. The data storage device also includes a non-volatile memory array and a controller coupled to the non-volatile memory array and further coupled to a mapped device. The controller is adapted to, in response to a first request from the host for access to the first address region of the device address space, perform a memory access operation at the non- volatile memory array. The controller is also adapted to, in response to a second request from the host for access to the second address region of the device address space, map the second request to the mapped device.
