Abstract: A method for manufacturing a memory having at least one stacked integrated circuit chip is firstly to remove a plurality of transitional weld structures from a first IC chip. A varied insulation layer is then formed on the first IC chip. The varied insulation layer is then processed by a laser beam to form a plurality of metal-disposed portions. A plurality of chip-conductive structures are then formed on the metal-disposed portions. A plurality of manufactured weld structures is formed on the chip conductive structures. A second IC chip having a plurality of original weld structures is then provided to the first IC chip. The original weld structures of the second IC chip are connected to the chip conductive structures of the first IC chip to form a stacked IC chip. The stacked IC chip is then mounted onto a memory substrate component to form a memory having the stacked IC chip.

Abstract: A download management system includes a server, a computer host and a storage device. The server stores an encrypted data, which is encrypted according to a certification signature. The computer host is communicatively connected to the server for executing a management program. The storage device is connected electrically to the computer host and includes the certification signature, wherein the download management execution program is capable of reading the certification signature from the storage device, downloading the encrypted data from the server, decrypings the encrypted data according to the certification signature to obtain a decrypted data, and storing the decrypted data in the storage device.

Abstract: A data secure system includes a computer host and a storage device having a certification signature. The computer host includes an encryption/decryption program, a data transceiver unit, an encryption module, and a decryption module. The data transceiver unit is communicatively connected to the storage device and an external device for receiving a raw data from the external device. The encryption module reads certification signature from the storage device via the encryption/decryption program, encrypts the raw data into an encryption data according to the certification signature, and stores the encryption data in the storage device. The decryption module reads the certification signature and the encryption data from the storage device via the encryption/decryption program and decrypts the encryption data according to the certification signature. Moreover, a method of storing and reading data is also provided.

Abstract: The invention discloses an information certification system including a data processing device and a portable storage medium. The portable storage medium includes a transmission interface and a memory array. The portable storage medium is removably coupled to the data processing device through the transmission interface. The memory array includes a hidden storage area. When a protected program is executed on the data processing device, the data processing device sends a certification request to the portable storage medium. The portable storage medium checks the certification request and selectively returns certification information stored in the hidden storage area back to the data processing device. Wherein, the certification information corresponds to the protected program.
