Memory devices having selectively-activated termination devices

A memory device, comprising:

• an input/output (I/O) node;
• a termination device;
• an array of memory cells in communication with the I/O node through the termination device;
• a termination register comprising a plurality of first fields and a plurality of second fields, wherein each first field of the plurality of first fields is configured to store a respective instance of address information, wherein each second field of the plurality of second fields corresponds to a respective first field of the plurality of first fields, and wherein each second field of the plurality of second fields is configured to store a respective termination value, and
• control circuitry, wherein the control circuitry is configured to compare an address received by the memory device to any address information stored in the plurality of first fields and, in response to the memory device receiving an address matching an instance of address information stored in the plurality of first fields, is configured to activate the termination device using the respective termination value stored in the second field corresponding to the particular first field storing the instance of address information matching the received address.

A memory system, comprising:

• a controller;
• and
• a plurality of memory devices in communication with the controller;
• wherein the controller is configured to load respective sets of termination information to a subset of memory devices of the plurality of memory devices;
• wherein each memory device of the subset of memory devices is configured to store its respective set of termination information to an array of non-volatile memory cells of that memory device;
• and
• wherein, for each memory device of the subset of memory devices, its respective set of termination information comprises address information of the memory system and one or more termination values to be used by that memory device to adjust an impedance characteristic of that memory device in response to receiving an address from the controller matching that address information.
