Methods and apparatuses for in-system field repair and recovery from memory failures

A method comprising:

• outputting a physical address responsive to a comparison between a received memory address and at least one remapped address, wherein the physical address corresponds to a location in a random-access memory (RAM);
• and
• updating remapping information to identify a particular address in response to a number of occurrences of errors in data read from a particular location based on the particular address satisfying a threshold.

An apparatus comprising:

• means for outputting a physical address responsive to a comparison between a received memory address and at least one remapped address, wherein the physical address corresponds to a location in a random-access memory (RAM);
• and
• means for updating remapping information to identify a particular address in response to a number of occurrences of errors in data read from a particular location based on the particular address satisfying a threshold.

A method comprising:

• a first step for outputting a physical address responsive to a comparison between a received memory address and at least one remapped address, wherein the physical address corresponds to a location in a random-access memory (RAM);
• and
• a second step for updating remapping information to identify a particular address in response to a number of occurrences of errors in data read from a particular location based on the particular address satisfying a threshold.

A non-transitory computer-readable medium comprising processor-executable instructions that, when executed by a processor, cause the processor to:

• output a physical address responsive to comparing a received memory address to at least one remapped address, wherein the physical address corresponds to a location in a random-access memory (RAM);
• and
• update remapping information to include a particular address in response to a number of occurrences of errors at a particular location based on the particular address satisfying a threshold.

A method comprising:

• detecting that data read from a memory includes an error, the memory comprising a plurality of pages;
• and
• storing an address of the data in a mode register based on detection of the error included in the data read from the memory, wherein the mode register is accessible to a host device configured to perform page address remapping.
