Volatility management for non-volatile memory device

A Central Processing Unit (CPU), comprising:

• an interface for communicating with a Memory Device (MD) that includes a configurable Non-Volatile Memory (NVM) configured to store temporary data designated for volatile storage and persistent data designated for non-volatile storage;
• and
• a processor configured to:
• designate a memory page in a virtual memory space as volatile or non-volatile based on data allocated to the memory page;
• define a volatility mode of operation for the MD based on whether the memory page is designated as volatile or non-volatile;
• and
• send a write command to the MD to write the data allocated to the memory page in the configurable NVM, wherein the defined volatility mode of operation is used by the MD to determine whether to write the data in both a first memory array of the configurable NVM and a second memory array of the configurable NVM or to write the data in the first memory array without writing the data in the second memory array.

A method of operating a Memory Device (MD), the method comprising:

• associating an address with a first location in a first memory array of a configurable Non-Volatile Memory (NVM) of the MD and with a second location in a second memory array of the configurable NVM, wherein the configurable NVM is configured to store temporary data designated for volatile storage by a Central Processing Unit (CPU) and persistent data designated for non-volatile storage by the CPU;
• receiving a write command to write data in the configurable NVM for the address;
• and
• in performing the write command, determining whether to write the data in the second location based on a volatility mode of operation set for the MD.

A non-transitory computer readable medium storing computer-executable instructions, wherein when the computer-executable instructions are executed by a controller of a Memory Device (MD), the computer-executable instructions cause the controller to:

• associate an address with a first location in a first memory array of a configurable Non-Volatile Memory (NVM) of the MD and with a second location in a second memory array of the configurable NVM, wherein the configurable NVM is configured to store temporary data designated for volatile storage by a Central Processing Unit (CPU) and persistent data designated for non-volatile storage by the CPU;
• receive a write command to write data in the configurable NVM for the address;
• and
• in performing the write command, determine whether to write the data in the second location based on a volatility mode of operation of operation set for the MD.
