Abstract: Methods, systems, and apparatus for receiving a request to access, from a main memory, a first cache line of a page of data; determining that the first cache line is not stored in the main memory and is stored in a secondary memory, and in response: transferring the first cache line of the page of data from the secondary memory to the main memory without transferring the entire page of data, wherein a remaining portion of the page of data remains stored in the secondary memory; updating a page table entry associated with the page of data to point to a location of the page of data in the main memory; and transferring the remaining portion of the page of data from the secondary memory to the main memory.

Abstract: Methods, systems, and apparatus for determining whether an access bit is set for each page table entry of a page table based on a scan of the page table with at least one page table walker, the access bit indicating whether a page associated with the page table entry was accessed in a last scan period; incrementing a count for each page in response to determining that the access bit is set for the page table entry associated with the page; resetting the access bit after determining whether the access bit is set for each page table entry; receiving a request to access, from a main memory, a first page of data; initiating a page fault based on determining that the first page of data is not stored in the main memory; and servicing the page fault with a DMA engine.

Abstract: A method of partitioning a data storage device that has a plurality of memory chips includes determining a number memory chips in the data storage device, defining, via a host coupled to the data storage device, a first partition of the data storage device, where the first partition includes a first subset of the plurality of memory chips, defining a second partition of the data storage device via the host where the second partition includes a second subset of the plurality of memory chips, such that the first subset does not include any memory chips of the second subset and wherein the second subset does not include any memory chips of the first subset.

Abstract: A data storage device may include an interface that is arranged and configured to interface with a host, a command bus, multiple memory devices that are operably coupled to the command bus and a controller that is operably coupled to the interface and to the command bus. The controller may be arranged and configured to receive a read metadata command for a specified one of the memory devices from the host using the interface, read metadata from the specified memory device and communicate the metadata to the host using the interface.

Abstract: Methods, systems, and apparatus for receiving a request to access, from a main memory, data contained in a first portion of a first page of data, the first page of data having a first page size; initiating a page fault based on determining that the first page of data is not stored in the main memory; allocating a portion of the main memory equivalent to the first page size; transferring the first portion of the first page of data from the secondary memory to the allocated portion of the main memory without transferring the entire first page of data; and updating a first page table entry associated with the first portion of the first page of data to point to a location of the allocated portion of the main memory to which the first portion of the first page of data is transferred.

Abstract: A method of storing data in a flash memory data storage device that includes a plurality of memory chips is disclosed. The method includes determining a number of memory chips in the data storage device, defining, via a host coupled to the data storage device, a first partition of the data storage device, where the first partition includes a first subset of the plurality of memory chips and defining a second partition of the data storage device via a host coupled to the data storage device, where the second partition includes a second subset of the plurality of memory chips. First data is written to the first partition while reading data from the second partition, and first data is written to the second partition while reading data from the first partition.
