Method and system for buffer allocation management for a memory device

A non-transitory processor-readable media comprising processor-readable instructions, such that, when executed by a processor, causes the processor to:

• identify a request to access a memory device, the memory array having an associated buffer memory;
• in response to the request, send a completion notification to a buffer manager accelerator, the completion notification indicating at least one command block address corresponding to at least one command block at a buffer memory block in the buffer memory, wherein a reference counter is associated with the buffer memory block;
• decrement, in response to a determination that an overflow counter is allocated to the reference counter, the overflow counter;
• determine whether a request count satisfies a reference threshold associated with the reference counter, wherein the reference threshold corresponds to a maximum storage size of the buffer memory block;
• and
• deallocate the overflow counter from the reference counter, in response to a determination that the request count satisfies the reference threshold.

A storage device, comprising:

• a non-volatile memory;
• a host interface configured to:
• generate at least one memory address corresponding respectively to at least one command block, the command block being associated with a command to a memory device;
• allocate the at least one memory address to a buffer addressing unit associated with a host interface, the at least one memory address including a buffer memory identifier associated with a buffer memory block and a buffer memory address associated with the buffer memory block;
• determine whether a request count associated with the buffer memory block satisfies a reference threshold;
• update, in accordance with a determination that the request count does not satisfy the reference threshold, the request count by incrementing a reference counter associated with the buffer memory block;
• allocate an overflow counter to the reference counter, in response to a determination that the request count satisfies the reference threshold;
• increment, in response to a determination that the overflow counter is allocated to the reference counter, an overflow count associated with the overflow counter;
• and
• decrement, in response to a determination that the overflow counter is allocated to the reference counter, the overflow count associated with the overflow counter;
• a flash interface configured to:
• reconstruct the command from the command block;
• and
• send the completion notification to the host interface, the completion notification indicating the command block address corresponding to the command block at the buffer memory block.
