Description of the Invention: [Technical Field] The present invention relates to a memory integration device and method, and more particularly to a high efficiency memory integration device and method. [Prior Art] Mobile storage devices, such as USB flash drives, are widely used in modern applications based on their portability and convenience. However, the action 〇 storage device often leaves some remaining storage space after storing a large amount of data. These remaining storage space may be difficult to use due to insufficient capacity. As a result, the remaining storage space of the mobile storage device will be wasted and left unused. Traditionally, software handling methods have been used to integrate multiple mobile storage devices. However, the above method of software processing will completely format the original data in the integrated mobile storage device, and then model a virtual mobile storage device, which will occupy more than 2 mobile storage devices. The entire storage space of the device. As a result, the original stomach material cannot be retained' and multiple mobile storage devices cannot be used alone, resulting in greatly reduced convenience in use. SUMMARY OF THE INVENTION The present invention relates to a memory integration device and method, which respectively establish a plurality of block slots in a peripheral storage device, so that the original data in the peripheral storage device can be destroyed without destroying the original data in the peripheral storage device. At least a portion of the remaining storage space of the plurality of peripheral storage devices is combined for reuse. According to a first aspect of the present invention, a memory integration device is provided, 3 201035769
