Devices and techniques for fatal error logging in memory device

Devices and techniques for fatal error logging in a memory device are described herein. For example a read request can be received for a component of the memory device. A fatal error indication of anerror that prevents correct execution of read request can be detected. Diagnostic information for the failure indication can be collected. A response to the read request can then be made with a portion of the diagnostic information as payload instead of the user data that would have occupied the payload had the read succeeded. Metadata in the response can be used to communicate an error code. 本公开涉及用于在存储器装置中记录致命错误的装置和方法。例如，可以接收对所述存储器装置的组件的读取请求。可以检测阻止正确执行读取请求的错误的致命错误指示。可以收集故障指示的诊断信息。然后，可以使用作为有效负载的所述诊断信息的一部分而不是在所述读取成功时占用所述有效负载的用户数据作出对所述读取请求的响应。所述响应中的元数据可以用于传递错误代码。
