Description

M365509 V. New Description: [New Technology Field] This case is a memory card technology used to store multimedia audio and video data, especially the memory card structure that can be used in conjunction with expansion devices. [Prior Art] As technology changes with each passing day, the traditional storage technology gradually enters the storage era of non-volatile memory. Non-volatile memory refers to the information storage memory of the stored data that does not disappear when the power is turned off. body. In non-volatile memory, whether the data in the memory can be rewritten as a standard at any time when using a computer can be divided into two categories, namely read-only memory (Read_〇nly mem〇ry, R〇M) and Flash memory. With the rise of low-cost computers, the Internet and the multimedia industry, the application range of flash memory storage products has become more extensive. In response to the capacity and processing speed of future audio and video data, there has been a major breakthrough in storage speed and capacity. This kind of flash memory storage products are mainly used for the backup and storage of text and multimedia audio and video negative materials, especially for multimedia audio and video materials, such as digital video, digital video and digital audio, etc., storage capacity and manufacturing cost. With the issue of content protection, especially the unit price and the protection mechanism for content, it is better to store the media unit price than other types of storage media. In the future, it may be replaced by the network = body audio and video data, because the current network frequency The width is not fast enough, the #Wedge type is taken, and the status of some large 3 M365509 type multimedia audio and video materials is accessed. On the other hand, ‘speed is not a substitute for optical storage media. Because the volume of optical storage media cannot be large, “:,” can only passively store data, and cannot give special merits, such as the ability to actively process data.
