Abstract: A volatile memory-based solid-state mass storage device adapted for use in a host system as a storage tier. The storage device includes a substrate on which is mounted a system interface, a control circuitry, and a plurality of substantially identical random access memory components that define at least one memory array. Each memory component of the memory array has associated therewith an input/output path, a width of the input/output path, and a burst length. The storage device is connected to the host system and uses parity information to provide redundancy data sufficient to correct a catastrophic failure of one of the memory components. The number of correctable bits to correct the catastrophic failure of one of the memory components equals the product of the width of the input/output path thereof and the burst length thereof.

Abstract: Memory technology adapted to store data in a binary format. Such technology includes a semiconductor memory device having memory cells, each having a substrate and at least three graphene layers that are oriented to define a graphene stack disposed in a plane. The graphene stack of each memory cell is connected to a bit line and to a ground connection so that a conductive path is defined in the plane of the graphene stack.

Abstract: A solid-state mass storage device for use with host computer systems, and methods of increasing the endurance of non-volatile memory components thereof that define a first non-volatile memory space. The mass storage device further has a second non-volatile memory space containing at least one non-volatile memory component having a higher write endurance than the memory components of the first non-volatile memory space. The second non-volatile memory space functions as a low-pass filter for host writes to the first non-volatile memory space to minimize read accesses to the first non-volatile memory space. Contents of the second non-volatile memory space are managed using a change counter.

Abstract: Systems and methods for maintaining cache synchronization in network of cross-host multi-hypervisor systems, wherein each host has least one virtual server in communication with a virtual disk, an adaptation layer, a cache layer governing a cache and a virtualization and acceleration server to manage volume snapshot, volume replication and synchronization services across the different host sites.
