    摘要： According to one embodiment, there is provided a memory system that is connected to a host apparatus. The memory system includes a transmitting port and a controller. The transmitting port transmits a transmission signal to the host apparatus. The controller includes a first output interface that is connected to the transmitting port and a second output interface that is connected to the transmitting port. The memory system is configured such that a drivability of an output from the first output interface is larger than a drivability of an output from the second output interface in a first mode.

    摘要： According to one embodiment, a storage system includes a plurality of memory nodes that are connected to each other in two or more different directions and a connection unit. The connection unit issues a command in response to a request from the outside. In the storage system, a plurality of logical memory nodes are constructed by allocating, to one logical memory node, memory nodes including at least one first memory node which stores data to be accessed by the command and a second memory node which stores redundant data of the data stored in the first memory node. The command includes a first address which designates one of the plurality of logical memory nodes and a second address which designates a storage position in a memory space allocated to each logical memory node.

    摘要： According to one embodiment, an information processing device includes a nonvolatile memory, assignment unit, and transmission unit. The assignment unit assigns logical address spaces to spaces. Each of the spaces is assigned to at least one write management area included in a nonvolatile memory. The write management area is a unit of an area which manages the number of write. The transmission unit transmits a command for the nonvolatile memory and identification data of a space assigned to a logical address space corresponding to the command.

    摘要： A storage device for a host device includes a non-volatile semiconductor memory and a control section configured to execute a delete process in response to a command from the host device to delete data stored at locations in the non-volatile semiconductor memory corresponding to a selected logical address included in the command. The delete process includes determining a selected mapping and at least one prior mapping of the selected logical address to physical addresses of the non-volatile semiconductor memory, and erasing or overwriting the data stored at the physical addresses.
