Volatile memory resource sharing in a memory system

A memory device, comprising:

• a plurality of processor cores;
• a volatile memory;
• and
• a non-volatile memory;
• wherein the memory device stores one or more programs comprising instructions for:
• allocating a first subset of processor cores to perform a plurality of memory access and management functions of a memory controller;
• allocating a second subset of processor cores of the memory device to perform a plurality of in-memory data processing functions as a data processor, wherein the plurality of in-memory data processing functions are configured to process, locally on the memory device, data extracted from, or to be stored in, the non-volatile memory;
• partitioning the volatile memory to (1) a first memory portion for storing address mapping data temporarily for the memory controller and (2) a second memory portion for storing payload data temporarily for the data processor;
• storing the address mapping data used by the memory controller and the payload data used by the data processor separately in the first memory portion and the second memory portion of the volatile memory;
• receiving, from the data processor, a caching request for storing target data temporarily;
• and
• in response to the caching request, in accordance with a determination that the second memory portion associated with the data processor has insufficient memory space to store the target data, storing the target data in the first memory portion via the memory controller.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions that, when executed by a memory device having a plurality of processor cores, a volatile memory, and a non-volatile memory, cause the memory device to perform:

• allocating a first subset of processor cores to perform a plurality of memory access and management functions of a memory controller;
• allocating a second subset of processor cores of the memory device to perform a plurality of in-memory data processing functions as a data processor, wherein the plurality of in-memory data processing functions are configured to process, locally on the memory device, data extracted from, or to be stored in, the non-volatile memory;
• partitioning the volatile memory to (1) a first memory portion for storing address mapping data temporarily for the memory controller and (2) a second memory portion for storing payload data temporarily for the data processor;
• storing the address mapping data used by the memory controller and the payload data used by the data processor separately in the first memory portion and the second memory portion of the volatile memory;
• receiving, from the data processor, a caching request for storing target data temporarily;
• and
• in response to the caching request, in accordance with a determination that the second memory portion associated with the data processor has insufficient memory space to store the target data, storing the target data in the first memory portion via the memory controller.
