Abstract:
1. A method of operating an electronic system, comprising: receiving a first command at two or more integrated circuit devices of the electronic system; determining that a common prior command that is received at each of the two or more integrated circuit devices is valid at only one of the two or more integrated circuit devices; and responding to the first command with the only one of the two or more integrated circuit devices for which the common prior command is valid; wherein the common prior command is received at each of the two or more integrated circuit devices prior to receiving the first command at the two or more integrated circuit devices; wherein the common prior command has an address or other identifier that uniquely specifies the only one of the two or more integrated circuit devices for which the common prior command is valid; wherein the common prior command initiates an operation on the only one of the two or more integrated circuit devices for which the common prior command is valid; and wherein the only one of the two or more integrated circuit devices for which the common prior command is valid responds to the first command in response to determining that the prior command was valid at that one of the two or more integrated circuit devices.
