ABSTRACT:
A recorder for an IC memory card (37) using a NAND-type flash memory assigns a single address to both audio and video source data, matching a structure of the NAND-type flash memory. Consequently, the audio and video source data may be recorded with a single address. The recorder includes a first memory (32) for accessing video data in units of a basic region of one page in the NAND-type flash memory, and a second memory (33) for accessing audio data in units of a dummy region of one page in the NAND-type flash memory. A first latch (34) and a second latch (35) match the timing of the video data and the audio data, respectively, accessible from the memories (32, 33). A page memory (36) records the video data output via the first latch (34) and then records the audio data output via the second latch (35) sequentially to thereby store data of a whole one-page unit. A controller (31) is provided for accessing the video data in units of a basic region from the first memory (32), accessing the audio data in units of a dummy region from the second memory (33), and enabling the first and second latches (34, 35) to be latched in order to sequentially record the audio and video data together in the page memory (36). Then a single address is assigned, in the IC memory card, to a one-page unit data stored in the page memory (36) to record the one-page unit of data, containing both audio and video information.
