Abstract: According to one general aspect, an apparatus may include a plurality of stacked integrated circuit dies. The dies may include a memory cell die configured to store data in a random access fashion. The dies may also include a look-up table die comprising a random access memory array that, in turn, includes a reconfigurable look-up table. The reconfigurable look-up table may be configured to perform a logic function. The reconfigurable look-up table may include a plurality of random access memory cells configured to store a look-up table to perform a logic function, and a local row decoder configured to activate one or more rows of memory cells based upon a set of input signals. The look-up table stored in the plurality of memory cells may be configured to be dynamically altered via a memory write operation to the random access memory array.

Abstract: Embodiments of the present invention include a drive-to-drive storage system comprising a host server having a host CPU and a host storage drive, one or more remote storage drives, and a peer-to-peer link connecting the host storage drive to the one or more remote storage drives. The host storage drive includes a processor and a memory, wherein the memory has stored thereon instructions that, when executed by the processor, causes the processor to transfer data from the host storage drive via the peer-to-peer link to the one or more remote storage drives when the host CPU issues a write command.

Abstract: According to one general aspect, a memory management unit (MMU) may be configured to interface with a heterogeneous memory system that comprises a plurality of types of storage mediums. Each type of storage medium may be based upon a respective memory technology and may be associated with performance characteristic(s). The MMU may receive a data access for the heterogeneous memory system. The MMU may also determine at least one of the storage mediums of the heterogeneous memory system to service the data access. The target storage medium may be selected based upon at least one performance characteristic associated with the target storage medium and a quality of service tag that is associated with the virtual machine and that indicates one or more performance characteristics. The MMU may route the data access by the virtual machine to the at least one of the storage mediums.

Abstract: A computing accelerator using a lookup table. The accelerator may accelerate floating point multiplications by retrieving the fraction portion of the product of two floating-point operands from a lookup table, or by retrieving the product of two floating-point operands of two floating-point operands from a lookup table, or it may retrieve dot products of floating point vectors from a lookup table. The accelerator may be implemented in a three-dimensional memory assembly. It may use approximation, the symmetry of a multiplication lookup table, and zero-skipping to improve performance.

Abstract: An Ethernet solid-state drive (Ethernet SSD or eSSD) system and corresponding method provide improved latency and throughput associated with storage functionalities. The eSSD system includes at least one primary SSD, at least one secondary SSD, an Ethernet switch, and a storage-offload engine (SoE) controller. The SoE controller may operate in a replication mode and/or an erasure-coding mode. In either mode, the SoE controller receives a first write command sent from a remote device to at least one primary SSD. In the replication mode, the SoE controller sends a second write command to the at least one secondary SSD to replicate data associated with the first write command at the at least one secondary SSD. In the erasure-coding mode, the SoE determines erasure codes associated with the first write command and manages distribution of the write data and associated erasure codes. The SoE controller may also receive read commands, data cloning commands and data movement commands from the remote device.
