Abstract: Disclosed herein is an electronic component that includes a substrate, a planarizing layer covering a surface of the substrate, a first conductive layer formed on the planarizing layer and having a lower electrode, a dielectric film made of a material different from that of the planarizing layer and covering the planarizing layer and first conductive layer, an upper electrode laminated on the lower electrode through the dielectric film, and a first insulating layer covering the first conductive layer, dielectric film, and upper electrode. An outer periphery of the first insulating layer directly contacts the planarizing layer without an intervention of the dielectric film.

Abstract: A drive device capable of preventing a drop in the data transfer rate, even when write instructions from a host device are given with commands having a short write data length. If the write end address of one of a plurality of ATA commands issued by a host device 2 is consecutive with the write start address of the next ATA command, a command analysis unit 11 has data writing to an SD card 1 by the consecutive commands performed in a single process. As a result, overheads when writing data to SD cards are incurred only once, allowing the transfer rate to be improved.

Abstract: A semiconductor memory device according to the present invention comprises a housing including a card bus connector for connection to a host device and having a PC card shape having a thickness of 5.0 mm, four SD memory cards housed in the housing and a control circuit for controlling transmission/reception of a signal between the card bus connector and the respective SD memory cards. The semiconductor memory device is suitably used as a recording medium of a host device for which a higher data transfer rate and a larger memory capacity are demanded. Further, a semiconductor memory device, which is attachable and detachable relative to the host device and thereby portable, and relatively inexpensively obtainable, can be provided, and is directly insertable into a laptop personal computer to be used.
