Abstract: A memory system may monitor a bit error rate in data read from a memory in the memory system. The memory system may determine that the monitored bit error rate satisfies an acceptable memory error condition. The memory system may adjust operation of the memory system to decrease the power consumption of the memory system, wherein the adjusted operation results in a new bit error rate monitored from data read from the memory that satisfies the acceptable memory error condition.

Abstract: Examples are disclosed that relate to handling noise interference on an interlink connecting hardware devices. One example provides a computing system comprising a first hardware device, a second hardware device, an interlink connecting the first hardware device and the second hardware device, a logic system, and a storage system. The storage system comprises instructions executable by the logic system to operate the interlink in an intermittently active mode, detect a noise interference scenario on the interlink, and in response, set a persistent active mode for the interlink.
