A built-in electrode type susceptor having excellent corrosion resistance and plasma resistance is obtained. A placement plate and a support plate made of ceramics are prepared, fixation holes are formed in this support plate, and feeding terminals consisting of a conductive composite ceramics are fitted into these fixation holes so as to penetrate through the support plate. A conductive material layer consisting of a conductive composite ceramics is formed on this support plate so as to come into contact with the feeding terminals, and the support plate and the placement plate are overlapped on each other via the conductive material layer on the support plate, and subjected to sintering and heat treatment under application of pressure, to thereby integrate these plates. Also, the conductive material layer is used as an internal electrode consisting of a conductive composite ceramics sintered body, to thereby obtain a built-in electrode type susceptor. At the time of overlapping and bonding the placement plate and the support plate, these may be bonded via a nonconductive layer having the same material as these plates.

A distribution server and includes a communicator that communicates with multifunction apparatuses via a network a menu generator that generates menu information based on information obtained by the communicator, the information including display capability information and job capability information for each multifunction apparatus. The menu information includes information for execution of a job and a menu name assigned for the job. A data memory stores the generated menu information and a distributor retrieves, from the data memory, menu information requested by the multifunction apparatus and distributes, via the network, the menu information to the requesting multifunction apparatus.

An error correction code of (N+M) words is configured by adding an ECC parity of M word (M is a natural number) to N words extracted at an interval of A words with respect to data of (A*N) words (A and N are natural numbers) inputted via an interface. A data distributor distributes (N+M) words to the respective (N+M) physical blocks to record by A words. In a case where a writing error has occurred, data recorded in a cell sharing page of the page and in a page of another physical block configuring the error correction code is read. A disappearing correction is carried out to the data of the cell sharing page by using the data, and thus the data of the cell sharing page is recovered and written. In this manner, in the multi-level nonvolatile memory, an error in writing of a certain page can be prevented from propagating to a written page sharing a cell.

A semiconductor recording apparatus includes a logical-to-physical conversion table 115 showing correspondence between a physical address of said semiconductor memory and a logical address and writes the table to a flash memory 120. On receiving a write command issued from a host device 200, a block management section 114 selects a physical block with reference to said logical-to-physical conversion table, and updates said logical-to-physical conversion table. A logical-to-physical conversion table initializing section 117 updates a physical address corresponding to each logical address of the logical-to-physical conversion table into an invalid address. Accordingly the apparatus can render the number of rewrites of physical blocks uniform irrespective of writing conditions.

A memory card controller for controlling data transfer between a host device that requests data transfer by issuing a command specifying a data amount and a memory card that executes a transfer operation from receipt of a transfer start instruction until receipt of a transfer end instruction. The memory card controller is provided with a clock start/end control unit 10 that suspends supply of a clock signal to the memory card when a data amount transferred from the memory card as a result of the transfer operation reaches a data amount specified by an nth command received from the host device, and resumes supply of the clock signal to the memory card if a subsequent command received with supply of the clock signal to the SD card in a suspended state specifies an address consecutive to an end address of data transfer requested by the nth command as a start address.

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.

An error correction code of (N+M) words is configured by adding an ECC parity of M word (M is a natural number) to N words extracted at an interval of A words with respect to data of (A*N) words (A and N are natural numbers) inputted via an interface 1. A data distributor 3 distributes (N+M) words to the respective (N+M) physical blocks to record by A words. In a case where a writing error has occurred, data recorded in a cell sharing page of the page and in a page of another physical block configuring the error correction code is read. A disappearing correction is carried out to the data of the cell sharing page by using the data, and thus the data of the cell sharing page is recovered and written. In this manner, in the multi-level nonvolatile memory, an error in writing of a certain page can be prevented from propagating to a written page sharing a cell.

In an apparatus for processing input N-bit digital video data with an error correction parity, the input N-bit digital video data includes each one sample of higher-order-N-bit data and a plurality of samples of lower-order-(M-N)-bit data, wherein M>N. An error correction circuit corrects an error of input N-bit digital video data, outputs error-corrected N-bit digital video data, and generates an error detection signal representing an error which can not be corrected. Further, a data combining circuit converts the error-corrected N-bit digital video data into M-bit digital video data, and an error classifying circuit classifies the error detection signal into a first error detection signal representing an error of the each one sample of the higher-order-N-bit data and a second error detection signal representing an error of the plurality of samples of the lower-order-(M-N)-bit data. An error concealment circuit performs an error concealment process for the converted M-bit digital video data based on only the first error detection signal.
