A device includes a host including a main memory, and semiconductor memory including a nonvolatile semiconductor memory, memory unit, and controller. The nonvolatile semiconductor memory stores first address information. The memory unit stores second address information as part of the first address information. The controller accesses the nonvolatile semiconductor memory based on the second address information. Third address information is stored in the main memory, and is part or all of the first address information. The controller uses the third address information when accessing the nonvolatile semiconductor memory if address information to be referred is not stored in the second address information.

Data reading and writing processing from and to a semiconductor memory and a memory of a host device by using first and second interface circuits

According to one embodiment, a memory device includes a nonvolatile memory, a volatile memory, a controller, and a board. The nonvolatile memory stores data. The volatile memory holds a part of the data stored in the nonvolatile memory. The memory controller controls the volatile memory and the nonvolatile memory. The nonvolatile memory, the volatile memory, and the memory controller are provided on the board. The memory controller transmits an interrupt signal to a request source, when the volatile memory does not have any data corresponding to an address which the request source requests to access.

Memory controller configured to transmit interrupt signal if volatile memory has no data corresponding to address requested from source

Memory system with block rearrangement to secure a free block based on read valid first and second data

A memory management device of an example of the invention controls writing into and reading from a main memory including a nonvolatile semiconductor memory and a volatile semiconductor memory in response to a writing request and a reading request from a processor. The memory management device includes a coloring information storage unit that stores coloring information generated based on a data characteristic of write target data to be written into at least one of the nonvolatile semiconductor memory and the volatile semiconductor memory, and a writing management unit that references the coloring information to determines a region into which the write target data is written from the nonvolatile semiconductor memory and the volatile semiconductor memory.

Memory management device predicting an erase count

According to one embodiment, the memory device includes a non-volatile memory, a volatile memory, and a controller. The controller carries out the transition to two different sleep states depending on a sleep instruction from the host device and saves sleep state information indicating the sleep state after the transition to the host-side storage device. Upon receiving a return instruction from the host device, the controller carries out return processing in accordance with the sleep state information stored in the host-side storage device.

Memory device, and information-processing device

According to one embodiment, a storage unit, a management unit that acquires attributes of communication apparatuses from a plurality of the communication apparatuses and stores identifiers of the communication apparatuses and the attributes in the storage unit in association with each other as communication apparatus information, and a selection unit that selects a distributor apparatus that is the communication apparatus distributing a content to the other communication apparatuses as a radio signal based on the communication apparatus information are included.

Data processor, content distribution system, and communication apparatus

[Problem] To provide a method for producing human corneal epithelial sheet, wherein the human corneal epithelial-derived cells obtained by culturing human corneal epithelial cells are cultured on an amnion substrate. [Solution] A method for culturing human corneal epithelial cells using mesenchymal stem cells as the feeder cells; and a method for culturing human corneal epithelial cells using a medium containing a ROCK inhibitor, a phosphodiesterase inhibitor, a MAP kinase inhibitor and a TGF-&#x3b2; receptor inhibitor in various combinations.

Data writing processing into memory of a semiconductor memory device by using a memory of a host device

According to one embodiment, a communication apparatus includes a radio interface unit that sends a data message to a receiver and extracts, when a message sent by the receiver via unicast with an optimized transmission rate is received, rate information indicating the optimized transmission rate of the receiver from the received message, a message processor that generates the data message, in which a multicast identifier indicating a multicast group is a destination, and outputs the data message to the radio interface unit, and a selector that selects, according to the rate information, a data message transmission rate to send the data message.

Communication apparatus and communication method

According to one embodiment, a communication apparatus includes a congestion degree calculating unit and an operation mode setting unit. The congestion degree calculating unit calculates a third congestion degree related to wireless communication based on a first congestion degree of first wireless communication and a second congestion degree of second wireless communication. In the first wireless communication, peer-to-peer communication is performed directly between communication apparatuses, and in the second wireless communication, communication is performed through a wireless communication device. The operation mode setting unit switches an operation mode of the first wireless communication based on the third congestion degree to either of a mode in which the communication apparatus transmits content or a mode in which the communication apparatus receives content.

According to one embodiment, a memory system is connectable to a host including a first memory. The memory system includes a non-volatile second memory, a volatile third memory, and a controller. The controller uses the third memory as a work memory, and executes data transfer between the host and the second memory. The controller receives a first command to change a power mode from the host. The controller transfers first data to the first memory and transfers second data to the second memory in response to the receipt of the first command. The controller transmits a response of completion of data transfer. The first data and the second data are included in third data. The third data is data in the third memory.

Memory system

According to one embodiment, a communication apparatus includes an operation mode storage unit that stores a mode in which the communication apparatus operates as a wireless base station or a terminal and a non-volatile memory, wherein a transmission message is output to the outside when the communication apparatus operates as the wireless base station, data included in a received reception message is stored in the non-volatile memory when the communication apparatus operates as the terminal, and when the communication apparatus operates as the wireless base station, after all data transmitted from a first external wireless base station is received, if a communication quality with the first wireless base station is less than a predetermined value, and no message is received from a wireless base station other than the first wireless base station, a channel selection and switching process is performed, and then the operation mode is changed from the terminal to the wireless base station.
