New description: [New technical field] This creation is about SD+, especially an SD card with multiple flash memories. [Prior Art] Due to the rapid development of electronic integrated circuit technology materials, the application of electronic integrated circuits is widely used. The products are not only powerful, but also the trend of products is slim and short. State, electronic dictionary, digital camera, digital camera and various digital products, etc. The Secure Digital Card (SD card) is the new storage medium. It is lighter, thinner and shorter than the popular SmartMedia or CompactFlash Card. It has high compatibility, low cost, large storage capacity and fast transmission speed. And with a variety of features such as confidentiality, suitable for mobile phones, PDAs, computers, and various multimedia data storage, transmission, etc., coupled with its unique anti-write switch design, it immediately became the darling of the current market. With the development of digital technology, many digital electronic products, such as digital cameras, digital cameras, multimedia players, digital projectors, digital sound recorders, etc., have been developed to reform the traditional audio and video products to achieve a small storage volume. The largest storage function, the above-mentioned assets, electronic products are mostly carried, it is necessary to rely on the compact SD card to store data, etc.; the core of the SD card is the flash memory, the flash memory can have more The operation of storing, reading, deleting, etc. of data; however, the capacity of the flash memory of the conventional SD card used as a storage medium for digital peripheral products is usually limited, so the size and volume of the sd M285764 card Under the same circumstances, how to make the SD card have a larger memory capacity is indeed a big topic worth exploring. [New Content] The purpose of this creation is to provide an SD card that increases the number of flash memory in the same size and volume to achieve the purpose of increasing the memory capacity. The SD card of the present invention includes: a first housing having a first top surface and a sidewall extending around the first top surface, the first top surface and the sidewall forming a first receiving space; a second a second top surface and a side wall extending around the second top surface, the second top surface and the side wall forming a second accommodating space; and a circuit board comprising at least a first flash memory, a flash memory, a control chip, and a passive component; the first flash memory is disposed adjacent to the second flash memory system, and the control chip and the passive component are disposed in the first flash memory or the The first housing, the circuit board and the second housing are coupled to each other in sequence, so that the first accommodating space and the second accommodating space accommodate the first Flash memory, the second flash memory, the control chip, and the passive component. Preferably, one side of the second housing has a plurality of slots. [Embodiment] Although the present invention will be fully described with reference to the drawings containing the preferred embodiments of the present invention, it should be understood that those skilled in the art can modify the creations described herein and obtain the creations. The effect. Therefore, it is to be understood that the following description is a broad disclosure of those skilled in the art and is not intended to limit the invention. M285764 Refer to the first picture, the second picture A and the second picture b, respectively, to create an exploded view of the SD card, a top view of the created SD card, and a cross-sectional view of the A-A line of the a picture. The first SD card 1 includes a first top surface 5 and a side wall 6 extending around the first top surface 5. The top surface 5 and the side wall 6 form a first volume. a second housing 4 having a second top surface 15 and a side wall 7 extending around the second top surface '15', the second top surface 15 and the side wall 7 forming a second space Having a space 8 and a plurality of slots 9 on one side of the second housing 4; and two circuit boards 3 including at least a first flash memory 10, a second flash memory 11, a control chip 12, and Passive component 13 (see Figure 3 a). ~ Please refer to the third A figure, the third B picture, the fourth a picture and the fourth B picture, respectively showing the top view of the circuit board, the b_b line sectional view of the third A picture, and the top view of the circuit board combined with the second housing And the cc line cross-section of the fourth A diagram' and with reference to the first figure, the second A picture and the second b picture. The first housing 2 is integrally formed of a plastic material, wherein the first top surface 5 is a label pasting area; the first flash memory 1 is disposed adjacent to the second flash memory 11 The pins 14 are sequentially and in parallel arranged on opposite sides of the first flash memory 10 and the second flash memory U. One end of the pin 14 is connected to the first flash memory 1 or The second flash memory 14 is connected to the circuit board 3 at the other end. The control chip 12 and the passive component π are disposed on one side of the second flash memory 11. The first housing 2, the circuit board 3, and the second housing 4 are coupled to each other in sequence, so that the first accommodating space and the second accommodating space 8 receive the first flash memory 10, The second flash memory 11, the control chip 7 M285764 12 and the passive component 13 form the original SD card 1, and the original SD card 1 achieves the most compact implementation space without reducing the structural strength. The passive component 13 is also received in the cavity 9 of the second housing 4. The first housing 2, the circuit board 3 and the second housing 4 are combined in an ultrasonic manner, and the bonding manner can further strengthen the first housing 2, the circuit board 3, and the second The bonding between the casings 4 is optimal for the plastic forming process, and the molded article is more resistant to impact and is not easily peeled off, so as to protect the first flash memory 10 of the circuit board 3, The second flash memory 11, the control chip 12, and the passive component 13 will be apparent to those skilled in the art after a detailed description of the preferred embodiment of the present invention, and can be carried out without departing from the scope and spirit of the following claims. Various changes and modifications are made, and the present invention is not limited to the embodiments of the embodiments set forth in the specification. For example, the positions of the first flash memory and the second flash memory in the embodiment may be interchanged.
