Block management for mass storage

A method, comprising:

• writing or storing information associated with a particular logical block address (LBA), wherein writing or storing information comprises writing or storing sector information in a sector location of a first block;
• rewriting or updating the information associated with the LBA, wherein rewriting or updating the information associated with the particular LBA comprises writing or storing rewritten or updated sector information in a sector location of a second block;
• and
• writing or storing the rewritten or updated sector information in a sector location of a third block, wherein the sector location of the third block corresponds to a location of the particular LBA in a sequence of LBAs that are associated with information written or stored in the third block wherein the third block is associated with a particular virtual logical block address (VLBA), and wherein the particular VLBA of the third block is a function of the LBAs that are associated with the information written or stored in the third block.

A controller configured to:

• write or store information associated with a particular logical block address (LBA) in a sector location of a first block of memory communicatively coupled to the controller;
• rewrite or update the information associated with the particular LBA in a sector location of a second block of the memory, wherein the controller being configured to rewrite or update the information associated with the particular LBA comprises the controller being configured to write or store rewritten or updated sector information in the sector location of the second block of the memory;
• and
• write or store the rewritten or updated sector information in a sector location of a third block of the memory, wherein the sector location of the third block corresponds to a location of the particular LBA in a sequence of LBAs that are associated with information written or stored in the third block wherein the third block is associated with a particular virtual logical block address (VLBA), and wherein the particular VLBA of the third block is a function of the LBAs that are associated with the information written or stored in the third block.

A memory system comprising:

• memory organized into blocks, wherein each block comprises a plurality of sector locations, wherein each of the sector locations is configured to store sector information;
• and
• a controller configured to:
• write or store information associated with a particular logical block address (LBA) in a sector location of a first block of the memory;
• rewrite or update the information associated with the particular LBA in a sector location of a second block of the memory, wherein the controller being configured to rewrite or update the information associated with the particular LBA comprises the controller being configured to write or store rewritten or updated sector information in the sector location of the second block of the memory;
• and
• write or store the rewritten or updated sector information in a sector location of a third block of the memory, wherein the sector location of the third block corresponds to a location of the particular LBA in a sequence of LBAs that are associated with information written or stored in the third block wherein the third block is associated with a particular virtual logical block address (VLBA), and wherein the particular VLBA of the third block is a function of the LBAs that are associated with the information written or stored in the third block.

A controller configured to:

• write or store information identified by a particular logical block address (LBA) in a sector location of a first group of blocks of memory communicatively coupled to the controller, the first group of blocks of memory comprising at least one block of memory and the information comprising sector information;
• and
• rewrite or update the information associated with the particular LBA in a free or available sector location of the first group of blocks of memory, wherein the controller being configured to rewrite or update the information associated with the particular LBA comprises the controller being configured to:
• write or store rewritten or updated sector information in the free or available sector location of the first group of blocks of memory;
• identify the rewritten or updated sector information as being current or new;
• identify the sector information associated with the particular LBA that had been previously written or stored as old;
• and
• write or store sector information written or stored in the first group of blocks of memory and identified as current or new in sector locations of a second group of blocks of memory in accordance with a sequential order of respective LBAs associated with the sector information written or stored in the first group of blocks of memory and identified as current or new, wherein the second group of blocks of memory comprise at least one block of memory and each of the second group of blocks is associated with a respective virtual logical block address (VLBA).

A memory system comprising:

• memory organized into blocks, wherein each block comprises a plurality of sector locations, wherein each of the sector locations is configured to store sector information;
• and
• a controller configured to:
• write or store information identified by a particular logical block address (LBA) in a sector location of a first group of blocks of the memory, the first group of blocks of memory comprising at least one block of memory and the information comprising sector information;
• rewrite or update the information associated with the particular LBA in a free or available sector location of the first group of blocks of memory, wherein the controller being configured to rewrite or update the information associated with the particular LBA comprises the controller being configured to:
• write or store rewritten or updated sector information in the free or available sector location of the first group of blocks of memory;
• identify the rewritten or updated sector information as being current or new;
• identify the sector information associated with the particular LBA that had been previously written or stored as old;
• and
• write or store sector information written or stored in the first group of blocks of memory and identified as current or new in sector locations of a second group of blocks of the memory in accordance with a sequential order of respective LBAs associated with the sector information written or stored in the first group of blocks of memory and identified as current or new, wherein the second group of blocks of memory comprise at least one block of memory and further wherein the controller is further configured to associate a respective virtual logical block address (VLBA) with each of the blocks of the second group of blocks.
