Abstract
Subject matter disclosed herein relates to determining that a portion of a memory is at least partially non-functional, replacing the portion of at least partially non-functional memory; and adjusting an error detection and/or correction process responsive to determining that the portion of the memory is at least partially non-functional and/or replacing the portion of at least partially non-functional memory.
Claims20
A method for operating a memory device, comprising:
- determining if a section of memory is at least partially non-functioning;
- replacing the section of memory that is at least partially non-functioning with a section of memory which is allocated for storing error codes,
- wherein replacing the section reduces a total amount of memory available for storing error codes;
- and
- wherein, after reduction of the total amount of memory available for storing error codes, the total amount of memory available for storing error codes does not increase.

A non-volatile memory device comprising:
- a memory, the memory including one or more sections of memory which are allocated for storing error codes and one or more sections of memory which are allocated for storing non-error codes;
- and
- a controller configured to replace memory locations in the one or more sections allocated for storing non-error codes that are determined to be at least partially non-functioning to memory locations in the one or more sections of memory which are allocated for storing error codes, thereby decreasing a total amount of memory which is available for storing error codes from an original level, wherein the total amount of memory which is available for storing error codes does not increase after being decreased.
An apparatus comprising:
- a plurality of integrated circuit memory chips;
- and
- a memory controller configured to:
- determine that one or more memory sections of the memory chips is at least partially non-functioning;
- and
- replace the one or more sections of memory that are at least partially non-functioning with one or more sections of memory that are allocated for storing error codes, thereby reducing an amount of memory which is available for storing error codes, wherein the amount of memory which is available for storing error codes does not increase after being reduced.
