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

Abstract

A method for write aggregation using a host memory buffer includes 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. The method further includes aggregating the data specified by the write commands in a host memory buffer maintained in memory of the host. The method further includes determining whether the data in the host memory buffer has aggregated to a threshold amount. The method further includes, 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.
