  • Patent number: 8341311
    Abstract: A flash memory system having the capability of streaming data directly from flash memory to the interface of a host computer in order to substantially reduce latency of to-host transfers, while also maintaining the capabilities for caching and overlapped flash I/O provided by RAM DMA transfers. When data is read from the flash memory, the data is transferred into the RAM buffer and at the option of the memory controller, directly (via an intermediate FIFO) to the host interface. This results in a desirable reduction in the latency of data transfer because as soon as the first byte of data is read from the flash memory by the DMA engine, the data will be transferred directly to the host interface. Because the data is also being transferred to the buffer RAM, preferred embodiments of the present invention still provide the advantages of using an intermediate transfer buffer.

  • Patent number: 7804985
    Abstract: Impact resistant circuit modules are disclosed for enclosing a die having a sensor area. Preferred modules include a flexible circuit and a die coupled thereto. The flexible circuit is preferably folded over compressible material to help absorb applied forces. A gap may be provided between sides of the die and the compressible material to help prevent peeling. A metal reinforcing layer may be bonded to the back of the die. A low modulus material including a patterned gap underneath the die may be used to absorb forces. A dry film adhesive may be placed between at least part of the upper surface of the die and the flexible circuit, preferably to provide further point impact resistance and protection. High and low modulus material may be combined in ruggedizing structures. Consumer devices employing such circuit modules are also taught, as well as module construction methods.

  • Patent number: 7759791
    Abstract: A system and method for assembling dual-die integrated circuit packages using thermocompression bonding or thermosonic bonding to bond a second die to a substrate opposite a first die bonded to the substrate. The second die is bonded using heat conducted through the first die to the substrate, and optionally through an underfill material. The first and second die are connected such that bumps are connected to common bonding pads on the substrate. Bumps on one of the die extend through openings in the substrate to connect to the common bonding pads. The bonding pads are within the perimeter of the first die.

  • Publication number: 20090294946
    Abstract: The present invention provides a system and method for selectively stacking and interconnecting leaded packaged integrated circuit devices. In preferred embodiments, the plastic body of one or more leaded packaged ICs bear conductive traces that create circuitry to provide stacking related electrical interconnections between the constituent ICs of a stacked module without the use of separate interposers or carrier structures. Typically, the circuitry is borne by the body of the upper one of the ICs of a two-IC leaded package stack to implement stacking-related connections between the constituent ICs.

  • Publication number: 20090160042
    Abstract: A system and method for combining a leaded package IC and a semiconductor die using a flex circuitry. The leaded packaged IC is disposed along an obverse side of a flex circuit. In a preferred embodiment, the lower surface of the body of the leaded packaged IC contacts the surface of the flex circuitry. The semiconductor die is disposed beneath the leaded package IC and, in preferred embodiments, disposed in a window that passes through at least a part of the flex circuitry and is attached to a conductive layer of the flex circuitry. In other embodiments, the semiconductor die is attached to the body of the leaded packaged IC. The flex circuitry preferably employs at least two conductive layers and, in preferred embodiments, the leaded packaged IC is connected to the flex circuitry at one layer while the semiconductor die is connected to the flex circuitry at the other conductive layer.

  • Patent number: 7508069
    Abstract: The present invention provides a system and method for combining a leaded package IC and a semiconductor die using a flex circuitry to reduce footprint for the combination. A leaded IC package is disposed along the obverse side of a flex circuit. In a preferred embodiment, leads of the leaded IC package are configured to allow the lower surface of the body of the leaded IC package to contact the surface of the flex circuitry either directly or indirectly through an adhesive. A semiconductor die is connected to the reverse side of the flex circuit. In one embodiment, the semiconductor die is disposed on the reverse side of the flex while, in an alternative embodiment, the semiconductor die is disposed into a window in the flex circuit to rest directly or indirectly upon the body of the leaded IC package. Module contacts are provided in a variety of configurations. In a preferred embodiment, the leaded IC package is a flash memory and the semiconductor die is a controller.
