Methods, systems, and computer readable media for write classification and aggregation using host memory buffer (hmb)

A method for write aggregation using a host memory buffer, the method comprising:

• caching data from host write commands in a host memory buffer accessible by a non-volatile memory system coupled to a host system via a bus;
• determining whether an amount of data in the host memory buffer is greater than or equal to a threshold amount;
• and
• in response to determining that the amount of data in the host memory buffer is greater than or equal to the threshold amount, fetching the data from the host memory buffer and writing the data to non-volatile memory of the non-volatile memory system.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

• fetching write commands and data specified by the write commands from a host over a bus to a non-volatile memory system coupled to the host;
• writing the data specified by the write commands from the non-volatile memory system over the bus to the host;
• and
• aggregating the data specified by the write commands in a host memory buffer maintained in memory of the host;
• determining whether the data in the host memory buffer has aggregated to a threshold amount;
• and
• in response to determining that the data has aggregated to the threshold amount, reading the data from the host memory buffer to the non-volatile memory system and writing the data to non-volatile memory in the non-volatile memory system.
