Logical address offset

A method, comprising:

• detecting a memory unit formatting operation that is initiated across a host interface of a memory unit and that formats the memory unit with a file system;
• operating the memory unit with a default logical address offset or an existing saved logical address offset prior to detecting the memory unit formatting operation;
• and
• calculating a new logical address offset in response to detecting the formatting operation, wherein the new logical address offset is equal to a difference in logical addresses between an end of a system data area and a beginning of a subsequent physical page of memory cells or a beginning of a subsequent physical block of memory cells.

A memory controller, comprising:

• control circuitry configured to:
• detect a memory unit formatting operation that is initiated across a host interface of a memory unit and that formats the memory unit with a file system;
• operate the memory unit with a default logical address offset or an existing saved logical address offset prior to detecting the memory unit formatting operation;
• and
• calculate a new logical address offset in response to detecting the formatting operation, wherein the new logical address offset is equal to a difference in logical addresses between an end of a system data area and a beginning of a subsequent physical page of memory cells or a beginning of a subsequent physical block of memory cells.

A memory system, comprising:

• a memory unit;
• and
• a memory controller coupled to the memory unit, wherein the memory controller is configured to:
• detect a memory unit formatting operation that is initiated across a host interface of the memory unit and that formats the memory unit with a file system;
• operate the memory unit with a default logical address offset or an existing saved logical address offset prior to detecting the memory unit formatting operation;
• and
• subsequently, in response to detecting the formatting operation, calculate a new logical address offset, wherein the new logical address offset is equal to a difference in logical addresses between an end of a system data area and a beginning of a subsequent physical page of memory cells or a beginning of a subsequent physical block of memory cells.
