Abstract: Example implementations include a method of receiving a host command identifier associated with a host command, determining a device command associated with the host command and a memory controller device, receiving a device command timestamp corresponding to a time of the determining the device command, and determining a debug record contemporaneously with the determining the device command, the debug record including the host command identifier, a device command identifier associated with the device command, and the device command timestamp. Example implementations also include a device operably coupled to a memory array, and with a memory controller device configured to receive a host command identifier associated with a host command, and configured to determine a device command associated with the host command and a memory controller device, and a debug record generator device operatively coupled to the memory controller device and configured to receive a device command timestamp corresponding to a time of the determined device command, and configured to determine a debug record contemporaneously with the determining the device command, the debug record including the host command identifier, a device command identifier associated with the device command, and the device command timestamp.
