A shape-molding structure of a memory card comprises a circuit substrate, at least one chip, and an encapsulant covering. The upper and lower surfaces of the circuit substrate have a circuit layer and a plurality of electric contacts, respectively. The chip is located on the upper surface of the circuit substrate and electrically connected with the circuit layer. The encapsulant covering is formed by using a mold to press encapsulant entering at least one encapsulant inlet provided on at least one side surface of the circuit substrate. The encapsulant covering encapsulates all the above components with only the electric contacts exposed. A trace mark of the encapsulant inlet remaining on the encapsulant covering is then cut to obtain a shape-molding structure of memory card with an smooth and intact outer appearance.

摘要:
A serial flash-memory chip has a serial-bus interface to an external controller. A flash-memory block in the serial flash-memory chip can be read by the external controller sending a read-request packet over the serial bus to the serial flash-memory chip, which reads the flash memory and sends the data back in a data-payload field in a completion packet. Data in a write-request packet is written to the flash memory, and a message packet sent back over the serial bus. The serial bus can be a Peripheral Component Interconnect (PCI) Express bus with bi-directional pairs of differential lines. Packets have modified-PCI-Express headers that define the packet type and data-payload length. Vendor-defined packets can send flash commands such as reset, erase, or responses after operations such as program or erase. A serial engine and microcontroller or state machine are on the serial flash-memory chip.

A Universal-Serial-Bus (USB) single-chip flash device contains a USB flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. USB packets from a host USB bus are read by a serial engine on the USB flash microcontroller. Various routines that execute on a CPU in the USB flash microcontroller are activated in response to commands in the USB packets. A flash-memory controller in the USB flash microcontroller transfers data from the serial engine to the flash mass storage blocks for storage. Rather than boot from an internal ROM coupled to the CPU, a boot loader is transferred by DMA from the first page of the flash mass storage block to an internal RAM. The flash memory is automatically read from the first page at power-on. The CPU then executes the boot loader from the internal RAM to load the control program.

摘要:
A Flash memory card is disclosed comprising a substrate, a Flash memory die on top of the substrate, a controller die on top of the Flash memory die, and an interposer coupled to with the controller die and on top of the Flash memory die wherein the interposer results in substantial reduced wire bonding to the substrate. The interposer can surround or be placed side by side with the controller die. A system and method in accordance with the present invention achieves the following objectives: (1) takes advantage of as large of a Flash memory die as possible, to increase the density of the Flash card by reducing the number of wire bond pads on the substrate and enabling insertion of the largest die possible that can fit inside a given card interior boundary; (2) more efficiently stacks Flash memory dies to increase density of the Flash card; and (3) has a substantially less number of bonding wires to the substrate as possible, to improve production yield.

摘要:
A method and system for providing a modular server-on-a-USB-flash-storage is disclosed. The server-on-a-USB-flash-storage is installed on a computing device. The method and system include providing USB interface logic, USB Local Control Program, a flash memory and a set of control button connectors, light emitting diodes (LED) connectors and a liquid crystal display (LCD) connector. The USB Local Control Program is coupled with the USB interface logic and the flash memory. The USB interface logic interacts with the computing device and allows the computing device to detect the server board. The USB Local Control Program boots up the server and prepares the computing device for use as the server. The flash memory stores a server image for the server, which is provided to the computing device using the USB Local Control Program. The control button connectors allow the server to be turned on, shut down gracefully, or restored to its initial state, by a single press of buttons connected to these connectors. The LED and LCD connectors allow the system status to be displayed or shown. Different server images can be installed onto the same computing device, be it a workstation, a PDA or a notebook computer, by simply swapping in and out the USB flash storage while the computing device is still running or “hot.”
