    Abstract: Systems, methods, circuits, devices, and apparatus including computer-readable mediums for managing tamper detections in secure memory devices. In one aspect, a secure memory device includes: a memory cell array, one or more tamper detectors each configured to detect a respective type of tamper event on at least part of the secure memory device, and a tamper detection status register storing one or more values each indicating a tamper detection status detected by a corresponding tamper detector. The secure memory device can include a command interface coupled to the tamper detection status register and configured to output the values stored in the tamper detection status register when receiving a trigger. The secure memory device can also include an output pin coupled to the tamper detection status register and be configured to automatically output the values stored in the tamper detection status register via the output pin.
