<P>PROBLEM TO BE SOLVED: To surely collect logs for deciding whether memory error detected by ECC is soft error or hard error, to minimize the occurrence of data correction by an ECC function taking a comparatively much time, in a case when the correction is possible, and to surely stop a system after the logs are completely collected even in a case when the correction is impossible. <P>SOLUTION: This computer system comprises a memory control part 21 having a function for detecting that the error occurs in data read out from a main storing device, and a cache control part 12 for reading the corrected data into a cache as usual, and having a function for inhibiting the writing to the main storing part of the cache and reading from the main storing device with respect to its block. in a case when the correction of error is possible. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
