Abstract: Technology for a memory device is described. The memory device can include an array of memory cells and a memory controller. The memory controller can receive a request to program a memory cell within the array of memory cells. The memory controller can select a current magnitude and a duration of the current magnitude for a programming set pulse based on a polarity of access for the memory cell, a number of prior write cycles for the memory cell, and electrical distances between the memory cell and wordline/bitline decoders within the array of memory cells. The memory controller can initiate, in response to the request, the programming set pulse to program the memory cell within the array of memory cells. The selected current magnitude and the selected duration of the current magnitude can be applied during the programming set pulse.

Some of the bond fingers are connected to the internal busses by conductive strips that wrap around the edges of the shelf. Some of the vias are connected to a whole group of external lands. Grouping the lands to a single via reduces the number of vias on the second surface of the package.

The package includes a first bond shelf, a second bond shelf and a third bond shelf. Mounted to the package is an integrated circuit which has a plurality of die pads. The die pads are arranged in a pattern of groups, wherein each group has a first die pad that is adjacent to a second die pad, and a third die pad that is adjacent to the second die pad and a first die pad of an adjacent group. Bond wires connect the first die pads to the first bond shelf, the second die pads to the second bond shelf and the third die pads to the third bond shelf, so that each adjacent die pad is connected to a different bond shelf. The staggered bond pattern maximizes the bond finger width of the package.

Abstract: An integrated circuit package which has internal bonding pads that are located on bonding shelves and coupled to internal conductive power/ground planes by conductive strips that extend along the edges of the shelves. The edge strips eliminate the need for conventional vias to couple the bonding pads to the planes and thus reduce the cost and size of the package and improve package electrical performance (less inductive, less resistance path). The bonding pads are coupled to an integrated circuit that is mounted to a heat slug attached to a top surface of the package. The heat slug can function as both a ground path and a thermal sink for the integrated circuit. The package may have capacitors coupled to the internal routing of the package to reduce the electrical noise of the signals provided to the integrated circuit. Additionally, the package may have multiple power planes dedicated to different voltage levels.

Abstract: An electronic package which has a heat sink that is attached to the lead frame of the package with a material that is both electrically and thermally conductive. The lead frame is also coupled to a first surface of an integrated circuit die with tape automated bonded (TAB) leads. The low thermal resistance of the heat sink increases the thermal performance of the package. The heat sink may also be mounted directly to the die with a conductive material so that the die is electrically grounded to the heat sink. The heat sink is then bonded to the leads of the lead frame that are dedicated to ground. In this embodiment, the heat sink provides the dual functions of a ground plate and a heat spreader.

Abstract: An integrated circuit package which utilizes a standard TAB tape that can couple a lead frame to one of a number of integrated circuit dies that have different outer dimensions. The TAB tape includes a sheet of polyimide which supports a plurality of conductive leads. The sheet has a rectangular center opening which provides clearance for the IC die. Adjacent to each edge of the center opening are a plurality of equally spaced contact openings which expose portions of the leads. The leads are coupled to the integrated circuit by attaching the contact portions to the surface pads of the die. The contact openings are located at various distances from the center opening so that the tape can accommodate different die sizes. The leads of the TAB tape are also attached to a lead frame through lead frame openings in the polyimide.
