摘要:
Interface parameters for a plurality of semiconductor devices, particularly parameters for output drivers (i.e. on chip driver) and terminations (i.e. on die termination) for double data rate dynamic random access memories, are aligned using a calibration reference which is common to the semiconductor devices and is connected to calibration connections on the semiconductor devices. The semiconductor devices are calibrated in succession, in each case individually, and the calibration connection on the respective semiconductor device which is currently performing calibration is connected to an internal calibration unit by an internal switching unit in the process, and the calibration connections on all other semiconductor devices are terminated to a high impedance internally.

Semiconductor memory modules and semiconductor memory systems using the same are described herein. The modules divide a conventional DIMM into a series of separate, smaller memory modules. Each memory module includes at least one semiconductor memory chip arranged on a substrate; CAwD signal input lines arranged on the substrate in a first predetermined line number and connecting one of the semiconductor memory chips to CAwD input signal pins on the substrate; and rD signal output lines arranged on the substrate in a second predetermined line number and connecting the one or a last semiconductor memory to a second number of rD output signal pins of the substrate. In a semiconductor memory system including the semiconductor memory modules, each memory module is separately connected to a memory controller by the CAwD signal input lines and the rD signal output lines in a respective point-to-point fashion.

摘要:
A semiconductor component package configuration includes a semiconductor chip mounted to a printed circuit board, and a substrate arranged between the semiconductor chip and the printed circuit board. The substrate is for routing the wiring terminals of the semiconductor chip to the printed circuit board. The substrate is connected to the printed circuit board by solder joints. A filler between the semiconductor chip and the substrate mechanically isolates the semiconductor chip and the solder joints. A metal layer, which is connected to solder joints, is applied to the substrate. At least one molded element of heat-dissipating material is applied to the metal layer and is connected in a heat-conducting manner to the metal layer. This provides the package configuration with an improved capability of conducting the lost power that is dissipated from the installed semiconductor chip, and the desired mechanical properties of the package arrangement are retained.
