    摘要: A test apparatus is for testing a memory device including a memory cell. The test apparatus includes a storage and a controller. The storage stores a first value. The controller executes, at a given timing, determining a second value which is a threshold limit value to read data of the memory cell correctly on the basis of an output of the memory cell, calculating a difference between the first value and the second value, outputting a deterioration information on the basis of the difference between the first value and the second value, and updating the first value stored in the storage to the second value.

    摘要: A memory control device is provided. The memory control device is configured to control access to a storage device including a plurality of storage areas. The memory control device includes a defect detecting unit configured to detect a defective area of a storage area into which data may not be stored. The memory control device also includes a storage processing unit configured to store defect information including address information of the defective area detected using the defect detecting unit into a memory area. A data writing unit is also included in the memory control device. The data writing unit is configured to write data, which has been written into the defective area, into a storage area other than the storage area comprising the defective area based on the defect information stored using the storage processing unit.
