Abstract
Embodiments of the present disclosure generally relate to SSD management of non-volatile memory blocks for writing multiple data streams. The SSD may include a non-volatile memory organized into a number of superblocks. Each superblock includes a number of streamblocks. In one embodiment, a method of operating the SSD includes receiving a data stream, identifying an open superblock, identifying an available streamblock from the open superblock, and assigning the data stream to the available streamblock from the open streamblock. In another embodiment, a method of operating the SSD includes receiving a first data stream and a second data stream, writing the first data stream to the first streamblock and writing the second data stream to the second streamblock, and calculating a combined XOR parity information for the first streamblock and the second streamblock.
