Abstract: Included are a flash memory onto which user data and parity data are recorded, an external interface unit which receives a first write command for instructing recording of the user data onto the flash memory, and a block managing unit which manages management information indicating whether parity data is valid or invalid. When the user data related to the first write command received through the external interface unit is recorded onto the flash memory 18, the block managing unit updates the management information so as to indicate that the parity data corresponding to the user data is invalid.

Abstract: A memory device controller interposed between a memory device and a host device includes a data communication unit configured to transfer data to and from the memory device in synchronization with a clock signal. The data communication unit supports a single edge synchronization mode in which data is transferred in synchronization with either one of a rising edge and a falling edge of the clock signal, and a double edge synchronization mode in which data is transferred in synchronization with both the rising edge and the falling edge. The data communication unit transfers data in the double edge synchronization mode when data is transferred by the memory device operating as a bus master.

Abstract: A host device 200A includes a data buffer 250. When data has been already written to a part of a physical block and data is additionally written to the physical block, it is determined whether or not the data written to the physical block is held in the data buffer. When the data is held, data is written to the block, and when an error exists, data in unit of physical blocks is rewritten. When the data is not held in the data buffer, a new physical block is required to be secured and then, data is written to the new block. Thereby, even when power is shut off or an error occurs during writing in the semiconductor memory device, destruction of data already written is prevented.

Abstract: A command analyzer 160 determines whether or not a first write command after power-on is issued. A new block reserve determinator 170 determines that a new physical block is reserved, in a case where the command analyzer 160 determines that first writing command after power-on is issued and the physical block corresponding to a logical address at which a host device requests transmit is in a written state. At this time, the semiconductor memory device writes data to the new physical block. Thereby, data written before power disconnection does not been destroyed.

Abstract: [Problem] As to a memory card drive for operating multiple memory cards in parallel and executing high speed reading and writing, the amount of current supplied to the memory card drive varies among apparatuses connected and supplying electric power to the memory card drive due to their different capabilities, and therefore apparatuses applicable to the memory card drive are limitd. [Means for Solving the Problem] In a recording device having one or more semiconductor memories mounted thereon, the number of semiconductor memories operating in parallel is restricted according to the available supply current of an accessing apparatus to which the recording device is attached.

Abstract: A printing apparatus having a paper positioning plate swingably supported and having two positions in operation. The first position temporarily stops the carrying of an edge of a paper sheet by engaging the edge. The second position allows the paper sheet to be freely carried. The portion of the paper positioning plate which engages the edge of the paper sheet is curved as an arc having its axis on the axis of swing of the paper positioning plate. Thus, the swinging motion of the paper positioning plate does not create a strong frictional force at the edge of the sheet of paper and hence no paper particles are produced.
