Direct Memory Address for Solid-State Drives

A solid-state drive, comprising:

• a plurality of memory buffers;
• a solid-state memory;
• and
• a controller, wherein the controller is configured to:
• perform a mapping of a window of memory addresses to a logical block addressing (LBA) range of the solid-state memory;
• responsive to receiving from a host a write request specifying a write address within the window of memory addresses, initialize a first memory buffer from the plurality of memory buffers;
• associate the first memory buffer with a first address range within the window of memory addresses such that the write address of the request is within the first address range;
• write to the first memory buffer based on the write address;
• and
• responsive to the buffer being full, persist contents of the first memory buffer to the solid-state memory using logical block addressing based on the mapping.

A method for direct memory access in a storage device, the method comprising:

• performing a mapping of a window of memory addresses to a logical block addressing (LBA) range of the storage device;
• responsive to receiving from a host a write request specifying a write address within the window of memory addresses, initializing a first memory buffer in the storage device;
• associating the first memory buffer with a first address range within the window of memory addresses such that the write address of the request is within the first address range;
• writing to the first memory buffer based on the write address;
• and
• responsive to the buffer being full, persisting contents of the first memory buffer to the storage device using logical block addressing based on the mapping.
