  • Publication number: 20110010484
    Abstract: During a programming data transfer process in a non-volatile storage system, recording units of data are transferred from a host to a memory device, such as a memory card. For each recording unit, pages of data are arranged in an order such that a page which takes longer to write to a memory array of the memory device is provided before a page which takes less time to write. Overall programming time for the recording unit is reduced since a greater degree of parallel processing occurs. While the page which takes longer to program is being programmed to the memory array, the page which takes less time to program is being transferred to the memory device. After programming is completed, the memory device signals the host to transfer a next recording unit. The pages of data may include lower, middle and upper pages.

  • Patent number: 7810235
    Abstract: A method is disclosed for making a connector for preventing electrostatic discharge during connection of a USB-type connector. The connector includes a grounding clip provided within a recess formed at least partially down into the surface of the second level of the base block. The grounding clip may have a proximal end affixed to a proximal end of a signal ground pin of the plurality of signal pins, though the grounding clip and signal ground pin may be coupled at other locations along their lengths. The connector including the grounding clip may be affixed to a semiconductor device. A portion of the grounding clip is provided at a height above the surface of the base block such that, when a shroud is slid around the connector, the shroud engages and remains in contact with the grounding clip. Accordingly, any electrostatic discharge built up in the shroud travels from the shroud, through the ESD grounding clip, to the signal ground pin where it is harmlessly dissipated.

  • Publication number: 20090307389
    Abstract: Techniques for switching access states for accessing non-volatile are disclosed. A plurality of non-volatile memory portions can be effectively presented as: (a) a single logical unit in a first access state (“single unit access state”) and (b) as multiple logical units in a second access state (“multi-unit access state”). An access switching system can be provided for a device that includes a plurality of non-volatile storage portions. As a result, the device can be operable to effectively switch between the first and second access states. In the first access state, the plurality of non-volatile storage portions can be effectively presented as a single logical unit for access by another device, thereby allowing the other device to effectively access the plurality of non-volatile storage portions from a single access point.

  • Publication number: 20090210637
    Abstract: 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.

  • Publication number: 20090165294
    Abstract: A low profile USB flash memory device, and methods of forming same, are disclosed. The USB flash memory device includes an integrated circuit memory portion and a USB connector. The memory portion and the USB connector may be integrally formed on the same substrate. The USB flash memory device includes a substrate on which is mounted one or more flash memory die, a controller die, passive components and an LED for indicating when the memory is being accessed. In contrast to prior art USB memory devices which used TSOP packages mounted on a printed circuit board, the semiconductor die of the present invention are affixed to the substrate and wire bonded in a SIP configuration. Omitting the encapsulated TSOP packages allows a reduction in the overall thickness of the USB flash memory device.

The grounding clip may have a proximal end affixed to a proximal end of a signal ground pin of the plurality of signal pins, though the grounding clip and signal ground pin may be coupled at other locations along their lengths. The connector including the grounding clip may be affixed to a semiconductor device. A portion of the grounding clip is provided at a height above the surface of the base block such that, when a shroud is slid around the connector, the shroud engages and remains in contact with the grounding clip. Accordingly, any electrostatic discharge built up in the shroud travels from the shroud, through the ESD grounding clip, to the signal ground pin where it is harmlessly dissipated.

  • Patent number: 7354314
    Abstract: A semiconductor device is disclosed including a sheathless connector having a grounding pin which protects against electrical shorts and damage upon a backwards insertion of the connector to a host device. If the electrical connector is inserted backwards, the grounding pin mates with the signal ground terminal of the socket, and avoids contact with the remaining terminals. As a result, the damage otherwise occurring upon a backwards insertion of prior art devices is avoided.
