Abstract
A data storage system includes a plurality of memory dies and interface circuitry, including a receiver configured to receive pulses of a read clock signal; an I/O contact pad coupled to the receiver via a signal path of an interface channel; and on-die-termination (ODT) circuitry coupled to the I/O contact pad and the receiver. The ODT circuitry includes a plurality of resistor pairs, each including a pull-up resistor selectively coupled to the signal path via a first switch, and a pull-down resistor selectively coupled to the signal path via a second switch; and ODT control circuitry configured to enable ODT at the interface circuitry by causing each of the switches to be closed during a first stage of the read operation, and disable ODT at the interface circuitry by causing each of the switches to be open during a final stage of the read operation.
