摘要： Example near-memory computing systems and methods are described. In one implementation, a system includes a host command processing system and a computational engine associated with a solid-state drive. In some situations, the computational engine includes multiple versatile processing unit slices coupled to one another. The multiple versatile processing unit slices are configured to perform different tasks in parallel with one another. The system also includes a host direct memory access module configured to access memory devices independently of a central processing unit.

摘要： Example computational storage systems and methods are described. In one implementation, a storage drive controller includes a non-volatile memory subsystem to process multiple commands. Multiple versatile processing arrays are coupled to the non-volatile memory subsystem. The multiple versatile processing arrays can process multiple in-situ tasks. A host direct memory access module provides direct access to at least one memory device.

摘要： A flow controller selects a direction (encryption/decryption) for an AES core according to quality of service parameters and a number of data words in encryption and decryption data buffers. A direction ratio may be calculated as a function of the quality of service parameters and the number of data words in the encryption and decryption data buffers. The flow controller selects the direction to reduce a cost function. The cost function may be at a minimum when a ratio of words in the encryption and decryption data buffers is the same as the direction ratio. A key management unit supplies keys according to the selected direction to the AES cores. Multiple AES cores may be used.

摘要： An LDPC decoder receives channel information and performs a bit flipping algorithm to correct unsatisfied checks with respect to a parity matrix H. The threshold condition for determining whether to flip a bit is a function of the channel information itself. A threshold Thk used to evaluate the threshold condition may vary between iterations based on the number of iterations, number of bits flipped in the previous iteration, and number of unsatisfied checks. A threshold Thki may be calculated for each bit position. Thki and the threshold condition may be a function of whether bit position i was flipped in a previous iteration. A binning approach for parameters of the threshold condition may be used to reduce hardware complexity.

摘要： A namespace is a declarative region that provides a scope to identifiers inside the namespace, which identifiers are the names of types, functions, variables, and the like. Namespaces are used to organize code into logical groups. A namespace is a collection of logical block addresses that are accessible to host software. The logical block addresses that comprise a namespace may be utilized to minimize overhead with smaller allocation of resources for multiple namespaces in SSD and to improve the operation of the OS by eliminating the need for defragmentation operations.

摘要： A storage device includes 3D NAND including layers of multi-level cells. When a shutdown command is received, whether a block is partially written is evaluated. If so, dummy lines are written after the last written wordline of the block. Partially written blocks may be those having a fill percentage less than a threshold. The threshold may be a function of the PEC count of the block. If a maximum retention time is exceeded by data stored in a partially written block, dummy lines may also be written to the block.

摘要： Example storage control systems and methods are described. In one implementation, a storage drive controller includes a non-volatile memory subsystem that processes multiple commands. The storage drive controller also includes a controller memory buffer (CMB) memory management unit coupled to the non-volatile memory subsystem. The CMB memory management unit manages CMB-related tasks including caching and storage of data associated with the storage drive controller.
