Embodiment Construction

[0028] Preferred embodiments of the present invention will be explained with reference to the drawings.

[0029] Features of a computer device according to an embodiment are described below. The computer device includes a main memory; a first memory diagnostic unit that identifies a faulty area or a defective area of ​​the main memory by executing a first memory diagnostic program; a storage unit that stores a relocatable second memory diagnostic program; and a second a memory diagnostic unit that loads a second memory diagnostic program stored in the storage unit into an area of ​​the main memory other than the defective area of ​​the main memory identified by the first main memory diagnostic unit (referred to as "non-faulty" or "non-defective") " area) and execute the second memory diagnostic.

[0030] That is, the computer device according to this embodiment diagnoses a main memory such as a dynamic random access memory (DRAM) in the computer device by executing a pluralit...

Abstract

A computer apparatus includes a main memory, a first memory diagnosis unit that determines a faulty area in the main memory by executing a first memory diagnostic program, and a storage unit that stores a relocatable second memory diagnostic program. Moreover, the computer apparatus includes a second memory diagnosis unit that loads the second memory diagnostic program into an area of the main memory other than the faulty area determined by the first memory diagnosis unit.

Description

[0001] Related Application Cross Reference [0002] This application is based on, and claims priority from, prior Japanese Patent Application No. 2008-258974 filed on October 3, 2008, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments discussed herein relate to a computer device and a method of diagnosing a memory. Background technique [0004] Computer equipment uses many kinds of diagnostic tests to diagnose defective parts of each built-in device. As an example of computer equipment, a diagnostic tool is disclosed, which runs a memory diagnostic test program to diagnose whether the storage function in the built-in memory is working normally, for example, whether it is possible to normally read predetermined data from the memory, write predetermined data to the memory normally, etc. data. See, for example, Japanese Laid-Open Patent Publication No. H6-4413. [0005] In the simplest form of diagnostic testing, memory di...
