Abstract: Devices and methods include transmitting loopback signals for monitoring operation of a memory device. In some embodiments, a memory device may receive a system clock signal from a host device and may generate an internal clock signal based at least in part on the system clock signal. In some embodiments, the memory device may generate a loopback signal based at least in part on the internal clock signal and may transmit the loopback signal via a loopback datapath associated with the memory device. A host device may compare the internal clock signal and the system clock signal to determine a fidelity of the internal clock signal. Termination values of the memory device may be adjusted based on the determined fidelity of the internal clock signal.

Abstract: Methods, systems, and devices for initializing memory systems are described. A memory system may transmit, to a host system over a first channel, signaling indicative of a first set of values for a set of parameters associated with communicating information over a second channel between a storage device of the memory system and a memory device of the memory system. The host system may transmit, to the memory system, additional signaling associated with the first set of values for the set of parameters. For instance, the host system may transmit a second set of values for the set of parameters, an acknowledgement to use the first set of values, or a command to perform a training operation on the second channel to identify a second set of values for the set of parameters. The memory system may communicate the information over the second channel based on the additional signaling.

Abstract: Methods and systems for testing memory systems are disclosed. A refresh rate for a test system including a number of memory devices may be controlled based on estimated power scenario of a memory system design. In response to performance of a number of refresh operations on the memory devices and based on the refresh rate, one or more conditions of the test system may be monitored to generate estimated performance data for the memory system design.
