Reconfigurable channel interfaces for memory devices

An apparatus, comprising:

• a first memory array coupled with a first data channel, the first data channel configured to communicate first data between the first memory array and a memory controller;
• a second memory array different than the first memory array and coupled with a second data channel, the second data channel configured to communicate second data between the second memory array and the memory controller;
• a first command/address (CA) interface coupled with a first control channel and associated with the first memory array;
• a second CA interface coupled with a second control channel and associated with the second memory array;
• and
• a selection component coupled with the first CA interface and the second CA interface and configured to selectively couple the second memory array with the first CA interface at a first time and to selectively couple the second memory array with the second CA interface at a second time, wherein the first CA interface is coupled with the first memory array at the first time and the second time.

A method, comprising:

• receiving a read command at a command/address (CA) interface coupled with a first control channel, a first memory array, and a second memory array, the first memory array coupled with a first data channel and the second memory array coupled with a second data channel different than the first data channel;
• identifying that the read command is for the second memory array;
• retrieving a set of data from the second memory array based at least in part on receiving the read command;
• and
• transmitting the set of data over the second data channel based at least in part on retrieving the set of data from the second memory array.

An apparatus, comprising:

• a first memory array coupled with a first data channel and a second memory array coupled with a second data channel;
• and
• a command/address (CA) interface coupled with a first control channel, the first memory array, and the second memory array and configured to receive a write command and identify that the write command is for the second memory array, wherein:
• the CA interface is configured to forward the write command to the second memory array over an internal channel;
• and
• the second memory array is configured to receive a set of data over the second data channel based at least in part on the write command and to write the set of data to the second memory array based at least in part on receiving the set of data.

A method, comprising:

• determining, by a host device, a size of information associated with an access command for performance by a memory device;
• determining a configuration of at least one of a plurality of command/address (CA) interfaces of the memory device based at least in part on determining the size of the information associated with the access command;
• and
• transmitting, to a CA interface of the plurality, a command indicating the configuration.
