1.

When a correctable data check is detected, immediately, correction is executed

 

 

 

 

 

according to the ECC. For data checks which cannot be corrected, rereading is

 

 

 

 

 

tried repeatedly up to the number of times specified in the "Read Retry Count",

 

 

 

 

 

"Write Retry Count" or "Verify Retry Count" parameter. However, if a

 

 

 

 

 

correctable error is detected during reading, data correction is executed at that

 

 

 

 

 

point according to the ECC.

 

 

 

 

2.

When error recovery has succeeded, processing of the command is continued.

 

 

 

 

3.

The contents of recovered errors are not reported.

 

 

 

 

4.

If unrecoverable errors have been detected, execution of that command is

 

 

 

 

 

terminated at that point.

 

 

 

 

5.

Transfer of data in blocks which include unrecoverable errors to the INIT is

 

 

 

 

 

done in accordance with the specification in the TB bit (read commands).
