Abstract: A method and a memory device are provided. One or more host central processing units (HCPUs) of the memory device may receive a workload from a host application. The workload includes an identifier (ID). The workload may be distributed to a central processing unit (CPU) of the memory device based on the ID. The workload may be distributed to channels of the memory device based on the CPU.

Abstract: A storage device includes non-volatile memory, a storage controller including a first controller processor connected to the non-volatile memory, and a second controller processor connected to the non-volatile memory, and shared memory to store a mapping table. The shared memory may be connected to the first controller processor and the second controller processor to share mapping table information between the first controller processor and the second controller processor. The storage controller may set a power mode of the first controller processor and the second controller processor based on an input/output intensity.

Abstract: A storage unit is disclosed. The storage unit may include storage for a component codeword. The component codeword may be stored in a block in the storage. The block may also store a block codeword. An interface may receive a read request for a chunk of data from a host and may send the chunk of data to the host. A circuit may read the component codeword from the block in the storage. An error correcting code (ECC) decoder may determine the chunk of data based at least in part on the component codeword.

Abstract: A multi-stream solid-state device (SSD) includes a normal-access memory associated with a first stream ID, a high-access memory having a higher endurance than the normal-access memory and being associated with a second stream ID, a controller processor, and a processor memory coupled to the controller processor, wherein the processor memory has stored thereon instructions that, when executed by the controller processor, cause the controller processor to perform identifying a data stream ID of an input data stream as one of the first and second stream IDs, in response to identifying the data stream ID as the first stream ID, storing the input data stream in the normal-access memory, and in response to identifying the data stream ID as the second stream ID, storing the input data stream in the high-access memory.
