TECHNIQUES FOR DYNAMIC PROXIMITY BASED ON-DIE TERMINATION
First Claim
Patent Images
1. A memory device comprising:
- one or more registers arranged to maintain on-die termination (ODT) settings; and
control circuitry to;
receive an indication that a command is to be executed by a separate memory device coupled with a same data channel;
read the one or more registers to determine what ODT setting to apply during execution of the command based on a first group identifier that indicates the separate memory device'"'"'s proximity to the memory device and based on whether the command is a read command or a write command.

Abstract
Techniques for proximity based on-die termination (ODT) include a memory device determining what ODT setting to apply during execution of a command by another memory device that is coupled to a same data channel as the memory device based on the memory device'"'"'s proximity to the other memory device and whether the command is a read command or a write command.

9. An apparatus comprising:
-
input/output (I/O) interface circuitry to couple with a first memory device; and circuitry to execute program logic, the program logic to; program a first register at the first memory device via the I/O interface circuitry to cause the first register to indicate multiple on-die termination (ODT) types to select when the first memory device is a terminating memory device for a first group of memory devices, the multiple ODT types based on whether a read command or a write command is to be executed by a second memory device included in the first group of memory device or is to be executed by a third memory device included in a second group of memory devices; and program a second register at the first memory device via the I/O interface circuitry to cause the second register to indicate at least two ODT types having separate ODT settings to apply based on whether a write command is to be executed by the second memory device or the third memory device. - View Dependent Claims (10, 11, 12, 13)

14. A storage device comprising:
-
a controller having input/output (I/O) interface circuitry to couple with multiple groups of memory devices via a same data channel; and a memory device of a first group of the multiple groups of memory devices, the memory device to include; one or more registers arranged to maintain on-die termination (ODT) settings; and control circuitry to; receive an indication that a command from the controller is to be executed by a separate memory device coupled with the same data channel; read the one or more registers to determine what ODT setting to apply during execution of the command based on a first group identifier that indicates the separate memory device'"'"'s proximity to the memory device and based on whether the command is a read command or a write command. - View Dependent Claims (15, 16, 17, 18, 19, 20)
