32 results about "CompactFlash" patented technology

CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly.

Differential Data Transfer For Flash Memory Card

A flash memory card includes a differential datapath that enables communications between the flash memory card and a host device to be performed using differential signals. The differential datapath can translate between the differential signals and card-specific signals that control read / write operations to the memory array of the flash memory card. The card-specific signals can be standard MultimediaCard, Secure-Digital card, Memory Stick, or CompactFlash card signals, among others. A host device that provides differential data transfer capability can include a similar differential datapath. By using differential data transfer rather than conventional clocked data transfer, overall data bandwidth between a flash memory card and a host device can be significantly increased, while simultaneously decreasing power consumption and pin requirements.

Flash toaster for reading several types of flash memory cards with or without a PC

A flash-memory-card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick. A converter chip converts the different card signals for transfer to a host personal computer (PC). Serial-to-parallel data conversion is performed for the smaller card formats with serial data interfaces, but not for CompactFlash with a parallel-data interface. A single slot has a 50-pin connector for CompactFlash cards or passive adapters. The passive adapters have the CompactFlash form factor and a smaller connector fitting smaller flash cards. Passive adapters have no components but simply wire the smaller connector to the CompactFlash connector. A pin mapping allows card-type detection by sensing the LSB address pins of the CompactFlash interface. A larger CompactFlash reader has multiple slots for each card type. The reader is connected to the PC by a cable, or located within the PC chassis in a drive bay. A stand-alone reader copies images from the flash-memory card to a removable disk media. Pressing a button initiates image transfer.

Cartridge for miniature optical data storage disc

A cartridge for an optical data storage disc includes a sheet metal sheath that is folded back on itself and a plastic insert that is inserted into the sheath. An opening is formed in the plastic insert for holding an optical data storage disc. The sheath includes two wall portions that are located on opposite sides of a bend area, where the sheet metal is folded. The two wall portions are attached to each other, preferably by spot-welding, to form a structurally stable sandwich that includes the plastic insert between the wall portions. The opening in the plastic insert becomes a cavity for holding the disc. A shutter opening is formed in one of the wall portions, and spindle openings are formed in both wall portions. A shutter covers the shutter opening when the cartridge is not operational to protect the disc. The disc is rotated by the spindle of an external disc drive which enters a central hole of the disc through the spindle openings. The use of sheet metal wall portions in conjunction with the plastic insert allows the cartridge to be made very thin. Used with an appropriate disc drive, the cartridge may be employed to provide a large amount of data to a CompactFlash® or other type of card slot.

Optical drive

A compact disk player includes a housing, an optical drive and a flash card reader. The housing has an internal chamber for accommodating the compact disk drive and the flash card reader, and a panel provided with a plurality of apertures. One of the apertures is for allowing a compact holder of the compact disk drive to pass in and out, whereas the other apertures are correspondingly provided with driving devices for reading from and writing to Memory Stick, CompactFlash, SecureDigital, MultiMedia, Smart Media, Extreme Digital, and PCMCIA cards. Using the above structure disposing the flash card reader and the optical drive in the same housing, materials required are decreased, occupied space is significantly reduced, and production cost is also lowered.

Portable memory device with multiple I/O interfaces wherein each I/O interface has respective protocol and device parameters are requested from one I/O interface using only respective protocol

A non-volatile storage device has first and second controllers that provide external access to non-volatile memory using different protocols. In response to a request from the first controller, the second controller retrieves parameters from the non-volatile memory and provides the retrieved parameters to the first controller. In one embodiment, the device parameters are USB descriptors, which may include a vendor ID, a product ID, a product string, and / or a serial number. The first controller may be a Universal Serial Bus (USB) card reader controller. Examples of the second controller include a Secure Digital (SD) controller, a CompactFlash (CF) controller, a MemoryStick controller, or a different type of controller that is able to provide external access to the non-volatile memory. The first controller provides the device parameters to a host during enumeration of the non-volatile storage device. The device parameters may be used to establish settings for the first controller.

Method and apparatus for processing digitally encoded audio data

An apparatus and a method for processing encoded digital audio data, wherein the digital audio data is encoded using one of a plurality of encoding formats. The present invention prevents encoded digital audio data that has been copied onto a particular type of data storage medium having a unique identifier, such as a compactflash memory card, from another one of the particular type of data storage medium from being playable in an audio playback device according to the present invention. In accordance with the present invention, an encoded audio data file is encrypted using a unique identifier associated with the data storage device and a second key, an associated decoder file is encrypted using a first key, and the encrypted data and decoder files are stored onto the data storage device. During playback, a digital signal processor decrypt the audio data file in response to the second key and decrypts the decoder file in response to the first key. Advantageously, the second key is generated in response to the unique identifier and a third key. This method of encrypting and playing back the audio data files stored in the data storage device prevents an apparatus according to the present invention from playing back audio data files from a particular type of data storage device having a unique identifier, when the audio data files have been copied from another one of the same type of data storage device.
