摘要 |
<p>A memory unit (40) such as a memory card is removably attachable to a data processing unit (1) such as a digital video recorder or an audio recording/reproducing unit. The memory unit (40) includes a non-volatile memory (42), a security unit (52) for protecting the security of data stored in the non-volatile memory (42), and an interface (41) that receives control data from the data processing unit (1). The control data is either first control data for a read or write operation with respect to the non-volatile memory, or second control data (different from the first control data) for a security operation of the security unit (52). Thus, such a security-type memory unit (40) is compatible with both a security type and a non-security type data processing unit. <IMAGE></p> |
