A signal detection device includes a measurer, an arithmetic operation unit, and signal period detector, and detects information such as a cardiac cycle with high accuracy by causing resonance of only a signal such as a heartbeat, the signal having strong pulse characteristics. The measurer measures a signal. The arithmetic operation unit performs nonlinear arithmetic operation processing for amplifying a pulse-like component of the signal measured by the measurer and suppressing a component other than the pulse-like component of the signal measured by the measurer. The signal period detector detects a periodic signal from an output of the arithmetic operation unit.

A digital still camera performs temporary high-speed writing when capturing a large number of images in a short time. Lengthy processing for erased block allocation or copying performed inside a nonvolatile storage device may disable the captured images to be written completely (may cause some frames to drop). A nonvolatile storage system includes an access device () and a nonvolatile storage device (). A button operation of a user on the access device () causes the mode of data writing to the nonvolatile storage device () to be switched. Temporary high-speed writing is performed into a physical block of a nonvolatile memory () from which a plurality of data pieces with different logical addresses and different data sizes have been erased. After the temporary high-speed writing, the written data is relocated into a user storage area (), and an erased block is newly allocated for subsequent temporary high-speed data writing.

An access deviceincludes an access speed information partfor informing an access speed required for data recording by the access deviceto a nonvolatile memory deviceThe nonvolatile memory device includes an access condition determination partfor determining an access condition required for meeting the informed access speed and an access area determination unitfor determining an access area according to the determined access condition. The access deviceinforms the required access speed to the nonvolatile memory devicein advance so that the access condition determination partand the access area determination partin the nonvolatile memory devicerealize data recording which meets the access speed informed in advance upon the data recording. Thus, it is possible to access all the nonvolatile memory devices at a desired speed regardless of difference in characteristics of the recording speed of each of the nonvolatile memory devices.

An access deviceinternally includes a logical-physical empty capacity management partfor obtaining information of a remaining capacity on a write once memory from a write once recording deviceA. In addition, the write once recording deviceA internally includes a physical empty capacity management partfor managing a remaining capacity on the write once memory and notifying the access device of the capacity. Prior to recording of file data, the access devicecan know an accurate remaining capacity of the write once recording device by: obtaining a remaining capacity of the write once memory from the write once recording deviceA; and comparing the capacity with a remaining capacity on an FAT to decide an actually-recordable remaining capacity for file data.

A nonvolatile storage device includes a controller and a nonvolatile memory. The controller has: a logical-physical address conversion part for converting a logical address designated by a host device into a physical address; and a boot code address conversion part for converting boot code address information designated by the host device into a physical address. After the power-on and before the logical-physical address conversion part becomes usable, a boot code is read from a part of region which can be accessed by designating a logical address from the host device by designating the boot code address information from the outside. Thus, it is possible to rapidly start the nonvolatile memory system after the power-on. In the state where the logical-physical address conversion part can be used, data-reading and data-writing are carried out by designating a logical address from the host device.

A music sound generation apparatus generates music-sound data based on sound source data, and outputs the music-sound data in synchronization with audio data obtained separately from the music-sound data. A channel assigner assigns a predetermined number of channels to the audio data and the music-sound data. A read control unit reads the audio data and the music-sound data in accordance with their assigned channels. A signal processing unit generates predetermined music by controlling the sound level of the read audio data and the read music-sound data on each assigned channel and mixing the audio data and the music-sound data. When detecting no unoccupied channel, the channel assigner determines, as an unoccupied channel, a channel selected from channels excluding the channel to which the audio data has been assigned. The signal processing unit performs sound elimination on the unoccupied channel.

Without corresponding to different address spaces between an access device and a nonvolatile memory device, the access device designates a file ID to manage a data storing state only in a physical address space in the nonvolatile memory device. The access device sends the nonvolatile memory device a transfer rate through a transfer rate transmitting unit. A filling-up rate calculating unit calculates a filling-up rate of a physical block corresponding to an assurance speed required by the access device. A remaining amount corresponding to the transfer rate is sought by using the calculated filling-up rate and is transmitted to a remaining amount receiving unit of the access device.

Musical sound data groups are recorded in nonvolatile memory banks by multiplexing the data without being compressed. A data reader reads the musical sound data in parallel from the plurality of nonvolatile memory banks according to reading instructions from an access module. In a musical sound generation system that cannot expect which pitch of the musical sound data is instructed to be read, since a plurality of pieces of data can be read in parallel from the plurality of nonvolatile memory banks, a sound production delay time can fall within an allowable time. Thus, by using a currently dominant large-capacity multi level NAND flash memory as a memory for the musical sound data, a high sound quality and compact musical sound generation system can be realized.

A memory controller, a nonvolatile storage device, an access device, and a nonvolatile storage system enable the storage architecture to be changed flexibly for intended use that can be changed variously. A nonvolatile storage system () sets a temporary area () and a normal access area of a nonvolatile memory () based on a use condition designated by a use condition designation unit () of an access device (). This structure enables the nonvolatile storage system () to change the temporary area () and the normal access area () to be prepared in the nonvolatile memory () by changing the use condition in accordance with intended use. In other words, the nonvolatile storage system () enables the storage architecture to be changed flexibly for intended use that can be changed variously.

In a memory controller according to the present invention, an external I/F unit receives ID information associated with data from the outside of a non-volatile memory, and a recording controller manages a recording position of the data in the non-volatile memory based on the ID information, so that an amount of time necessary for the retrieval of rights information based on the ID information is reduced.

When a write command is issued, new data is written into a free physical block of a nonvolatile memory (). Here, if data of the same logical block has been written already, the block is erased and a recording state is judged by a recording state judgment unit (). A physical block is swapped according to the number of write processes performed. Thus, it is possible to effectively perform a swap without increasing the number of write processes in a particular area, thereby increasing the lifetime of a nonvolatile storage module.

In a storage having a nonvolatile RAM of destructive read type, the number of restorations attributed to data read from the nonvolatile RAM is decreased, and the overall life of the storage is prolonged. In a storage having a nonvolatile RAM of destructive read type and a volatile RAM and holding the same data in the nonvolatile and volatile RAMs, data is read out of the volatile RAM in reading and data is written in both volatile and nonvolatile RAMs in writing.

When an access device accesses a nonvolatile memory device, the nonvolatile memory device or the access device detects or calculates a temperature T of the nonvolatile memory device. A temperature-adaptive control part of the nonvolatile memory device controls an access rate to a nonvolatile memory on the basis of the temperature T. Accordingly, the control part controls the rate so that the temperature T of the nonvolatile memory devices cannot exceed a limit temperature Trisk. In this manner, a nonvolatile memory system can eliminate a risk of a burn when ejecting the semiconductor memory device and can read and write data at a high speed.
