    • An IC card capable of a high-speed data transmission to/from a data transmission apparatus which is low in processing capability, is provided. The IC card of the present invention comprises: a controlling section which generates a data packet by adding management information including information regarding a data length of the data packet, and which divides the above-mentioned data packet to generate data blocks wherein a data length of the data block is designated from the data transmission apparatus; and a communicating section which sends an interrupt signal to the above-mentioned data transmission apparatus when the above-mentioned data block which includes the above-mentioned management information is to be sent, and does not send the above-mentioned interrupt signal to the above-mentioned data transmission apparatus when a data block which does not include the above-mentioned management information is to be sent, in a case where a plurality of the above-mentioned data blocks which compose the single above-mentioned data packet are sent to the above-mentioned data transmission apparatus.
    • 提供能够对处理能力低的数据传输装置进行高速数据传输的IC卡。 本发明的IC卡包括:控制部分,通过添加包括关于数据分组的数据长度的信息的管理信息来生成数据分组,并且将上述数据分组划分以生成数据块,其中数据长度为 从数据发送装置指定数据块; 以及当包含上述管理信息的上述数据块要发送时,向上述数据传输装置发送中断信号的通信部分,并且不向上述发送上述中断信号 在将不包含上述管理信息的数据块发送到上述数据分组的多个上述数据块的情况下,发送上述数据发送装置 上述数据发送装置。

    • A source block (B0) and the logical page number ("8") of a write target page are identified from the logical address of the write target page. Data objects (DN8, DN9, ..., DN12) to be written, which a host stores in a page buffer (2), are written into the data areas (DA) of the pages (Q0, Q1, ..., Q4) of a destination block (Bn), starting from the top page (Q0) in sequence. The logical page number ("8") of the write target page is written into the redundant area (RA) of the top page (Q0). The physical page number ("6=8-2") of the write target page is identified, based on the logical page number ("8") of the write target page and the page offset ("2") of the source block (B0.) . When notified by the host of the end of the sending of the data objects (DN8, ..., DN12), the data items (D13, ..., D31, D0, D1, ..., D7) in the source block (B0) are transferred to the pages (Q5, Q6, ..., Q31) in the destination block (Bn) via the page buffer (2) sequentially and cyclically, starting from the page (P11) situated cyclically behind the write target page (P6) by the number ("5") of pages of the data objects (DN8, ..., DN12).
    • 从写入目标页面的逻辑地址识别写入目标页面的源块(B0)和逻辑页码(“8”)。 要写入的要写入的数据对象(DN8,DN9,...,DN12)被写入页面(Q0,Q1,...)的数据区域(DA) Q4),从首页(Q0)开始。 写入目标页面的逻辑页码(“8”)被写入首页(Q0)的冗余区域(RA)。 基于写目标页的逻辑页号(“8”)和源块的页偏移(“2”),识别写目标页的物理页号(“6 = 8-2”) (B0。)。 当主机通知数据对象(DN8,...,DN12)的发送结束时,源中的数据项(D13,...,D31,D0,D1,...,D7) 块(B0)从循环地位于写入后的页(P11)开始,经由页缓冲器(2)依次循环地传送到目的地块(Bn)中的页(Q5,Q6,...,Q31) 目标页(P6)由数据对象(DN8,...,DN12)的页数(“5”)。
