摘要:
A memory module has a two-plate heat sink attached by rivets. A front plate contacts the flat surfaces of memory chips on a front surface of the module printed-circuit board (PCB) substrate, while another back plate contacts chips on the back surface of the substrate. The plates contact the substrate along the top edge opposite the connector edge, and along the upper half of the substrate's side edges. Holes in the substrate allow for rivets or other fasteners to pass through to firmly attach the plates to the substrate, prevent wobble. Four top-edge slots are cut in the plates near the top edge, between the rivets along the top edge. The top-edge slots allow air to flow underneath the plates, in small gaps between memory chips, and between the plate and the substrate. The added air flow underneath the plates helps cool the heat-sink plates, reduce hot spots and failures.

摘要:
A memory module has memory chips in stacks. The lower memory chip in a stack has pins that are soldered to pads on the module substrate. A hollowed printed-circuit board (PCB) has a hollow opening on the bottom with about the same width, length, and depth as the top cap of the lower memory chip. The hollowed PCB fits over the top cap of the lower memory chip and has lower pads on its lower surface but outside of the hollow opening. The lower pads are soldered to the top shoulders of the pins of the lower memory chip. An upper memory chip has pins that are soldered to pads on the upper surface of the hollowed PCB. The hollowed PCB has a metal trace that re-routes a second bank-select signal from a no-connect pin of the lower memory chip to a bank-select pin of the upper memory chip.
摘要:
A low-profile Universal-Serial-Bus (USB) connector includes a substantially flat base structure that is received in the lower section of a conventional female USB connector, and includes metal contacts formed on an upper surface of the base structure. Wobble or vertical play is reduced by rails extending along side edges of the base structure that are partially inserted into gaps formed between the metal case and base structure of the female USB connector. Between metal contacts on the low-profile USB connector are raised ribs (dividers) that prevent undesirable damage or contamination to the metal contacts. The connector base structure of the low-profile USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip.
摘要:
Memory chips are assembled into a stack with an insertion-pin frame between pins of two stacked memory chips. The insertion-pin frame is not bent or formed into 3-dimensional shapes but is flat, improving use in standard surface-mount processes such as solder printing onto the insertion-pin frame. Flat insertion pins held to the flat insertion-pin frame by necks are soldered to top shoulders of pins on a lower chip. Then bottom feet of pins of an upper chip are soldered to the insertion pins. The necks are punched away or broken to release the insertion-pin frame from the insertion pins that are soldered to the assembled stacked chips. An insulated wire jumper can be placed under the pins to jumper chip-select connections, or a bridge between insertion pins can be formed from the insertion-pin frame. Holding tabs to the bridge are removed with the insertion pins or by punching.

摘要:
A slim male Universal-Serial-Bus (USB) connector fits on only one side of the connector substrate in a standard female USB connector. Wobble or vertical play is reduced by locking depressions in the slim male USB connector that engage metal springs on a metal case that surrounds the female USB connector, locking the two connectors together. Between metal contacts on the slim USM connector are dividers that help fill in gaps when the two connectors are connected together, further reducing play. End rails on the slim USB connector fill in gaps on the sides. The connector substrate of the slim male USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip. The connector is wider than the standard width for a better fit. A slim female USB connector for assembly use with the slim male USB connector is also disclosed.

摘要:
A multi-light-emitting diode (LED) display for a USB flash drive produces a visually dazzling display. When accessed, a USB flash controller drives pulses onto an activity signal that increments a counter on a pattern-decoding generator. The pattern-decoding generator decodes the count and drives signals to data outputs. The data outputs connect to LED's, turning LED's on and off according to a display pattern. The pattern can be programmed by the USB flash controller into the pattern-decoding generator, or can be a hardwired pattern. Marquee patterns having a lit LED appearing to move down a line of LED's have more visual appeal than single LED indicators. Each data line can drive two LED's in different parts of a dual display, reducing costs. Multi-color LED's can be used to improve variety. The multiple LED's and the pattern-decoding generator can be mounted on a flexible PCB.
