Abstract: An electronic control unit has a microcomputer and a backup RAM, which stores its data irrespective of ON/OFF of an engine ignition switch. The backup RAM stores a main data in its storage area, and two checkup data in its storage areas, respectively. The two checkup data are calculated as a two-byte data from the main data of a 4-byte floating points type data and equal to each other. The microcomputer executes a data storing operation in the order of one checkup data, the main data and the other checkup data. The microcomputer determines that the main data is correct when either one of the checkup data is determined correct.

Abstract: Attempts have been made to increase the number of pins of packages accompanying the trend toward fabricating integrated circuits highly densely and in smaller sizes. The present invention provides technology for improving reliability in fabricating packages of the surface-mounted type that have increased number of pins. That is, when the packages are mounted on the wiring substrate, the lead pins that receive load from the axial direction exhibit bending strength which is smaller than the junction strength of solder at the junction portions. To achieve this object, the lead pins are made of a material having large resiliency such as a fiber-reinforced material, a transformation pseudo elastic material, an ultra-high tension material, or a heat-resistant ultra-high tension material.
