SELF-REPAIRABLE SEMICONDUCTOR AND ITS METHOD

Title:

SELF-REPAIRABLE SEMICONDUCTOR AND ITS METHOD

Document Type and Number:

Japanese Patent JP2005183929

Kind Code:

A

Abstract:

To provide a self-repairable semiconductor equipped with multi function units.

The self-repairable semiconductor is equipped with multi function units which perform the same function and have an auxiliary function unit. The semiconductor is equipped with one or more perfect or partial spare function units, when a defect of the auxiliary function unit which is accumulated to form the semiconductor is detected, its auxiliary function unit is changed so as to be replaced with an auxiliary function unit in a perfect or partial spare function unit. The reconfiguration is realized by a switching device related to the auxiliary function unit. The defective function unit or auxiliary function unit may be periodically detected in operation and/or may be detected manually while a power source is connected after assembling.
