    Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data. An SSD controller may manage reading and writing data to the flash memory. The SSD may include an automatic stream detection logic to select a stream identifier responsive to attributes of data. A garbage collection logic may select an erase block and program valid data in the erase block into a second block responsive to a stream ID determined the automatic stream detection logic. The stream ID may be determined after the garbage collection logic has selected the erase block for garbage collection.

    Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data and may support a plurality of device streams. A SSD controller may manage reading and writing data to the flash memory, and may store a submission queue and a chunk-to-stream mapper. A flash translation layer may include a receiver to receive a write command, an LBA mapper to map an LBA to a chunk identifier (ID), stream selection logic to select a stream ID based on the chunk ID, a stream ID adder to add the stream ID to the write command, a queuer to place the chunk ID in the submission queue, and background logic to update the chunk-to-stream mapper after the chunk ID is removed from the submission queue.

    Abstract: Inventive aspects include a key value store engine including non-volatile memory configured to store key-value inode descriptors each including a key and an associated value. The key value store engine can include a volatile memory to store a key hash tree and a collision hash tree. The key hash tree can include nodes each having a hash of one of the keys. The collision hash tree can include nodes each having a collided hash associated with two or more different keys. Each of the nodes of the key hash tree can include a collision flag indicating whether two or more different hashes correspond to a collided hash. The volatile memory can store a collision linked list including linked list nodes each having a key-value inode number indicating a location of a corresponding key-value inode descriptor stored in the non-volatile memory. The key value store engine can include a key value logic section.

    Abstract: A memory device configured to restore data based on power supply being blocked during programming of a storage device includes a first area including a first data column that is to be programmed, a second area configured to store restoration data of the first data column, and a processor configured to identify a program state of the first data column programmed in a first stripe of the storage device, and complete programming of the first data column based on the program state of the first data column. The processor is further configured to determine that the programming of the first data column has stopped, to generate a second data column by combining the restoration data with a stopped portion of the first data column, and to program the second data column in a second stripe.

    Abstract: A storage device is disclosed. A first storage media may store data. The first storage media may be of a first storage type and may be organized into at least two blocks. A second storage media may also store data. The second storage media may be of a second storage type different from the first type, and may also be organized into at least two blocks. A controller may manage reading data from and writing data to the first storage media and the second storage media. Metadata storage may store device-based log data for errors in the storage device. The drive-based log data may include a first log data for the first storage media and a second log data for the second storage media. An identification circuit may identify a suspect block in the at least two blocks in the first storage media and the second storage media, responsive to the device-based log data.
