Abstract: There is provided a novel storage system in which the number of signal lines will not increase even if the number of storage devices to be connected in a RAID system increases, and a novel data transfer method to enable a high-speed data transfer even when the transfer rate of the IDE device side is low. A RAID system (10) which is a storage system in which a RAID controller (11) connected to an ATA host and a plurality of IDE devices (12A to 12D, and 22A to 22D) are connected by an IDE bus, characterized in that at least two or more IDE devices are connected to one channel of the IDE bus and said RAID controller and each of said IDE devices are connected by a common data bus and a common address bus within the same channel.

Abstract: The present invention provides an SDIO controller, an SDIO wireless communication card, an SDIO wireless communications module, and a method for transmitting write data from an SDIO host device to an SDIO application. Specifically, the SDIO controller is a single-chip semiconductor device connecting an SDIO-compliant SDIO host device with a plurality of applications via an SD bus, wherein the controller includes: (a) an SD interface operably connectable with the SDIO host device to decode commands received from the SDIO host device, and to return a response to the SDIO host device; (b) one or more application interfaces; and (c) a temporary memory operably connected between the SD interface and the one or more application interfaces.

Abstract: A versatile SDIO host controller capable of connecting to standardized general interfaces is provided. An SDIO host controller as a one-chip semiconductor integrated circuit device comprising: at least one core of an SDIO host, the core including an SD host engine and an SD host register set and memory that control the SD host engine; a plurality of CPU interfaces that control the SDIO host; and at least one selector that selects among the CPU interfaces. In particular, the SDIO host controller preferably comprises at least an ATA interface and an ATA-SD protocol conversion engine.
