By Jonathan CorbetApril http://www.google.com/patents/US8555116 20, 2016 LSFMM 2016 One of the key advantages of persistent memory is that it is, for lack of a better word, persistent; data stored there will be available for recall in the future, regardless of whether the system has remained up in the meantime. But, like memory in machine check general, persistent memory can fail for a number of reasons and, given the quantities in which it is expected to be deployed, failures are a certainty. How should the operating system and applications deal with errors in persistent memory? One of the first plenary sessions at the 2016 Linux Storage, Filesystem, and Memory-Management Summit, led by Jeff Moyer, took on this question. machine check exception Error handling with traditional block storage is relatively easy: an I/O request will fail with an EIO error, and the application, assuming it is prepared, can handle the error in whatever way seems best. But persistent memory looks like memory to the system, and memory errors are handled differently; in particular, they can trigger a low-level machine-check error. Some systems can recover from that machine check, others will be forced to reboot. Either way, the system has to be able to handle the problem. Time for a bit of terminology that caused some confusion in the session. Jeff was talking in particular about errors in "load" operations — reading from persistent memory using normal CPU instructions. Those were differentiated from "reads," which are file operations performed with a system call like read(). Similarly, "stores" (using memory operations) and "writes" (file operations) are seen differently. Errors with reads and writes can be returned via the normal system call status; errors with loads and stores are a bit more complicated. In cases where a machine check from a load operation is recoverable, the kerne

In the memory system, a memory device generates an error-detection code based on an address transmitted via an address bus and transmits the error-detection code to a memory controller. The memory controller transmits an error indication to the memory device in response to the error-detection code. The error indication causes the memory device to remove the received address and prevent a memory operation. Images(7)Claims(28) What is claimed is: 1. A first integrated circuit, comprising: at least one transmitter operable to transmit, in association with a command, data and an associated address to a second integrated circuit; and a receiver operable to receiv
