Training procedure change determination to detect attack

Abstract

Methods, systems, and devices for training procedure change determination to detect an attack are described. A host device may perform one or more training procedures to train aspects of a memory device (e.g., a dynamic random-access memory (DRAM) component). A training procedure may depend on a current (e.g., present, within a threshold duration) metric associated with the memory device, such as a current channel metric for a channel between the memory device and the host device. The host device, memory device, or another device, may store a set of reference values associated with a training procedure and may compare a result of a training procedure to a reference value of the set to determine whether the training procedure has changed. If the training procedure or a related value has changed, the memory device may disable one or more features of the memory device to protect against a potential attack.
