Non-volatile memory systems utilizing storage address tables

A method for managing data, the method comprising:

• in a non-volatile memory system comprising a non-volatile memory, a plurality of memory die command managers in operative communication with the non-volatile memory, and a command manager in operative communication with the plurality of memory die command managers, the non-volatile memory comprising a plurality of die arrange into a plurality of channels of die, wherein each channel of die is managed by a different memory die command manager of the plurality of memory die command managers and each die comprises a set of non-volatile memory cells and associated circuitry for managing a physical operation of the set of non-volatile memory cells:
• receiving at the command manger a host write command with associated data, the host write command associated with a host logical block address;
• buffering the data;
• communicating a command request from the command manager to a memory die command manager of the plurality of memory die command managers, the command request comprising a size and a location of the buffered data;
• identifying, with the memory die command manager of the plurality of memory die command managers, independent of a host logical block associated with the data, a free die of the plurality of die of the channel of die manage by the memory die command manager that is idle and available to store the data;
• storing the buffered data at a physical block address at the free die;
• generating an entry in a first address table, the first address table containing the physical block address associated with a virtual logical block address;
• communicating the virtual logical block address to the command manager;
• and
• generating an entry in a second address table, the entry in the second address table associating the virtual logical block address with the host logical block address.

A non-volatile memory system comprising:

• non-volatile memory comprising a plurality of die, wherein each die comprises a set of non-volatile memory cells and associated circuitry for managing a physical operation of the set of non-volatile memory cells and where the set of the non-volatile memory cells and the associated circuitry for each die are formed on a single separate substrate and wherein the plurality of die is arranged into a plurality of channels of die;
• a plurality of means for managing a channel of die, wherein each means for managing a channel of die manages a different channel of die of the plurality of channels of die, and wherein each means for managing a channel of die is further for:
• identifying, independent of a host logical block address associated with the data, a free die of the plurality of die of a channel of die managed by the means for managing a channel of die that is idle and available to store data;
• storing the data at a physical block address at the free die;
• generating an entry in a first address table, the first address table associating a physical block address where the data is stored with a virtual logical block address;
• and
• means for generating an entry in a second address table, the second address table associating the virtual logical block address with a host logical block address for the data received with a host write command.
