1. A semiconductor storage apparatus managing system for managing an apparatus lifetime of a semiconductor storage apparatus having a semiconductor memory area for storing data and a defective block substituting area for substituting a defective block in the semiconductor memory area, comprising:

  • a consumed block number detecting section that detects a number of consumed blocks in the defective block substituting area; and

    a lifetime notifying section that predicts the apparatus lifetime of the semiconductor storage apparatus based on a result of the consumed block number detecting section and gives a notice of a result of the prediction;

    wherein the lifetime notifying section predicts the apparatus lifetime based on a worst value of a number of generation of acquired defective blocks in a unit time of the defective block substituting area.
