  • Patent number: 10289596
    Abstract: A memory device includes command logic allowing for a command protocol allowing interruption of a first command sequence, such as a page write sequence, and then to proceed directly to receive and decode a second command sequence, such as a read sequence, without latency associated, completing the first command sequence. Also, the command logic is configured to be responsive to a third command sequence after the second command sequence and its associated embedded operation have been completed, which completes the interrupted first command sequence and enables execution of an embedded operation identified by the first command sequence. A memory controller supporting such protocols is described.
