Data partitioning scheme for non-volatile memories

A memory system comprising:

• a user interface;
• a non-volatile memory;
• and
• a processor for storing data in the non-volatile memory, wherein the processor is configured to:
• receive, from the user interface, a user indication of a priority of the data;
• and
• direct the non-volatile memory to store the data based on the priority.

A memory system, comprising:

• a non-volatile memory;
• and
• a host processor for storing data in the non-volatile memory, wherein the host processor is configured with a file system and a memory driver, and wherein the file system is configured to:
• determine a priority associated with the data;
• identify, based on the priority, a logical address at which to store the data;
• and
• provide a write request to the memory driver to program the data in the non-volatile memory, wherein the write request includes the logical address.

A method of storing data in a non-volatile memory using an electronic system, the method comprising:

• assigning the data a high priority;
• storing the data in the non-volatile memory based on the assigned high priority;
• determining when the data has been backed up to another storage system;
• assigning the data a standard priority subsequent to the determination;
• and
• programming the data in the non-volatile memory based on the assigned standard priority.

An electronic system comprising:

• a non-volatile memory;
• and
• a processor configured to execute a plurality of modules to store user data in the non-volatile memory, the plurality of modules comprising:
• a union file system comprising a first file system and a second file system, wherein the union file system provides the user data to the first file system to indicate that the user data has a higher priority or to a second file system to indicate that the user data has a lower priority;
• and
• a memory driver for receiving write requests from the union file system and directing the non-volatile memory to store the user data.

A method of storing data in a non-volatile memory, the method comprising:

• receiving a logical address associated with the data;
• determining a priority of the data based on the received logical address;
• and
• storing the data in the non-volatile memory based on the priority.

A memory system for storing data, the memory system comprising:

• a non-volatile memory comprising a plurality of blocks;
• and
• a processor configured to:
• determine a priority of the data;
• identify one of the blocks in the non-volatile memory in which to store the encoded data;
• program at least one identifier in a first portion the identified block, wherein the identifier indicates the determined priority;
• and
• direct the non-volatile memory to store the data in a second portion of the identified block.

A method of reading data from a non-volatile memory, the method comprising:

• identifying a block of the non-volatile memory to access;
• reading a first portion of the block to access a first identifier;
• selecting an error correcting code based on the first identifier;
• reading a second portion of the block to access data;
• and
• decoding the data using the selected error correcting code.
