Metadata-based transaction management

The invention relates to metadata-based transaction management. The host device may transmit a read command to the memory device. Based on the read command, the host device may receive a data set from the memory device. The host device may also receive metadata associated with the data set. Based on the metadata, the host device may determine whether the data set is the data requested by the read command, data requested by a previous read command, or data not requested by the host device, or some combination. If the data set is the data requested by the read command or a previous read command, the host device may process the data set accordingly. If the data set is data that is not requested by the host device, the host device may discard the data set and retransmit the read command. 本申请案是针对基于元数据的事务管理。主机装置可将读取命令发射到存储器装置。基于所述读取命令，所述主机装置可从所述存储器装置接收数据集。所述主机装置也可接收与所述数据集相关联的元数据。基于所述元数据，所述主机装置可确定所述数据集是否是由所述读取命令请求的所述数据、由前一读取命令请求的数据或未被所述主机装置请求的数据，或某种组合。如果所述数据集是由所述读取命令或前一读取命令请求的所述数据，那么所述主机装置可相应地处理所述数据集。如果所述数据集是未被所述主机装
