摘要：Memory retry logic to improve the resilience of system memory operationswith respect to system errors or faults which prevent a memory read operation frombeing completed on a first attempt by allowing the memory to retry the operation once.The memory retry logic detects the occurrence of an improper response from thesystem element requesting a memory read operation when attempting to initiate thesystem bus operation for reading the data from memory to the requesting element and,if an improper response indicating that the requesting element is not accepting the busoperation request is detected, stores the memory operation request and the requesteddata and retries the data transmission on the next available bus cycle. If the memoryreceives an improper response of a specified type during a bus operation of a memoryburst, the memory will terminate the operation and proceed to the next requestedoperation.
