Abstract:
A built-in self repair (BISR) circuit for a multi-port memory and a method thereof are provided. The circuit includes a test-and-analysis module (TAM) and a defect locating module (DLM) coupled to the TAM. The TAM tests a repairable multi-port memory to generate a fault location and determines whether the test generates a port-specific fault candidate according to the fault location. If a port-specific fault candidate is generated, the DLM generates a defect location based on the fault location and provides the defect location to the TAM so that the TAM can determine how to repair the repairable multi-port memory according to the defect location. If no port-specific fault candidate is generated in the test, the TAM determines how to repair the repairable multi-port memory according to the fault location.
Abstract:
The present invention provides a package structure of optical sensitive device. The package structure includes a silicon substrate, an optical sensitive device, a supporting pad, a transparent plate and a plurality of conductive wires. The optical sensitive device is positioned on the silicon substrate, and the transparent plate is fixedly positioned on the supporting pad and corresponds to the optical sensitive area of the optical sensitive device. The transparent plate can be positioned on the substrate, and the electrical wires are electrically connected between the optical sensitive device and the substrate. A molding material is applied the periphery of the optical sensitive device and the substrate to prevent the electrical wires from exposed and damaged, thereby resulting in virtually eliminating particle containment
