Data reliability and integrity may be compromised when memory resources used to store the data reach elevated temperatures. A sensor in the memory resource may monitor the temperature of the memory resource in real-time. A comparator in the memory resource may indicate a high temperature condition to a memory controller. The memory controller, in response to the high temperature condition, can restrict or halt data flow to the memory resource. When the real-time temperature of the memory resource falls below a defined threshold, the memory controller may resume data flow to the memory resource.
