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.
