Flexible sub-channel selection in a shared communication channel

Abstract

A system performs operations including: storing a first value in a first memory location used for selecting a sub-channel of a plurality of sub-channels in a communication channel, each of the plurality of sub-channels corresponding to one or more memory components of a plurality of memory components of the memory device, wherein the first value specifies that a sub-channel selecting function is enabled; receiving, through the communication channel, a command directed to the memory device; responsive to receiving the command, storing a second value in a second memory location, wherein the second value is obtained from the command; determining that the second value matches a third value stored in a third memory location, wherein the third value stored in the third memory location comprises a preset value corresponding to a first component of the plurality of components of the memory device; and executing, by the first component, the command.
