MEMORY UNCORRECTABLE ERROR HANDLING TECHNIQUE FOR REDUCING THE IMPACT OF NOISE

Techniques for handling uncorrectable errors occurring during memory accesses reduce the likelihood of mis-correction of errors due to the presence of noise. When an uncorrectable memory error is detected in response to an access to a memory device, a memory controller managing the interface to the memory halts issuing of access requests to the memory device until a predetermined time period has elapsed. In-flight memory requests are marked for retry, and responses to pending request are flushed. A calibration command may be issued after the predetermined time period has elapsed. After the predetermined time period has elapsed and any calibration performed, the requests marked for retry are issued to the memory device.
