System and method to control memory failure handling on double-data rate dual in-line memory modules via suspension of the collection of correctable read errors

A method of controlling a dual in-line memory module (DIMM), comprising:

• determining, by a memory controller of the information handling system, that a read transaction from the DIMM results in a correctable read error;
• providing, by the memory controller, interrupts to a processor of the information handling system each time a read transaction between the memory controller and the DIMM results in the correctable read error;
• receiving, by a failure predictor instantiated by the processor, the interrupts;
• accumulating, by the failure predictor, a count of the interrupts;
• and
• providing, by the failure predictor, a first error indication when the count exceeds a first error threshold;
• wherein in accumulating the count the method further comprises:
• receiving a first in time interrupt;
• suspending the accumulation of the count for a first duration of time in response to receiving the first in time interrupt;
• and
• resuming the accumulation of the count after the first duration of time;
• wherein in resuming the accumulation of the count the method further comprises:
• receiving a first subsequent interrupt;
• incrementing the count each time the predictor receives the first subsequent interrupt;
• and
• decrementing the count in accordance with an error leak rate.

An information handling system, comprising:

• a processor;
• a dual in-line memory module (DIMM);
• and
• a memory controller coupled to the DIMM, the memory controller configured to
• determine that a read transaction from the DIMM results in a correctable read error, and to provide interrupts to the processor each time the read transaction from the DIMM results in a correctable read error;
• wherein the processor includes an interrupt handler configured to instantiate a failure predictor, the failure predictor to receive the interrupts, to accumulate a count of the interrupts, and to provide a first error indication when the count exceeds a first error threshold, wherein in accumulating the count, the failure predictor receives a first in time interrupt, suspends the accumulation of the count for a first duration of time in response to receiving the first in time interrupt, and resumes the accumulation of the count after the first duration of time, wherein in resuming the accumulation of the count the failure predictor receives a second subsequent interrupt, increments the count each time the predictor receives the first subsequent interrupt, and decrements the count in accordance with an error leak rate, and wherein the first duration of time is based upon a first transient condition on the information handling system.
