Non-volatile memory controller processing new request before completing current operation, system including same, and method

A non-volatile memory system comprising:

• a first memory configured to store meta data from a non-volatile memory;
• a second memory configured to store meta data from the first memory;
• and
• a memory controller configured to, in response to a received first request,
• load meta data from the first memory into the second memory,
• change the meta data loaded into the second memory,
• load the changed meta data into the first memory;
• and
• wherein the meta data includes at least one of address information, erase count information, memory block information, non-volatile memory state information, and non-volatile memory management information.

A non-volatile memory system comprising:

• a first memory configured to store meta data from a non-volatile memory;
• a second memory configured to store meta data from the first memory;
• and
• a memory controller configured to, in response to a received request, load at a least a portion of the meta data from the first memory into the second memory, change at least a portion of the loaded meta data, and load at least the changed portion of meta data from the second memory into the first memory.

A non-volatile memory system comprising:

• a first plurality of non-volatile memory chips, each of the first plurality of non-volatile memory chips being configured to store a first type of data and a second type of data, the first type of data including meta data;
• and
• a plurality of channels, each of the plurality of channels being connected to at least one non-volatile memory chip among the first plurality of non-volatile memory chip;
• a first memory configured to store meta data from a non-volatile memory;
• a second memory configured to store meta data from the first memory;
• a memory controller configured to, in response to a received first request,
• load meta data from the first memory into the second memory,
• change the meta data loaded into the second memory,
• load the changed meta data into the first memory;
• and
• wherein the meta data includes at least one of address information, erase count information, memory block information, non-volatile memory state information, and non-volatile memory management information.
