ELECTRONIC DEVICE MANAGING CORRECTED ERROR AND OPERATING METHOD OF ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18295457 titled 'ELECTRONIC DEVICE MANAGING CORRECTED ERROR AND OPERATING METHOD OF ELECTRONIC DEVICE

Simplified Explanation

The patent application describes an electronic device with a memory module and a processor. The device can detect and correct errors in the memory module and determine the risk level of the corrected error based on an error log. If the risk level is high, the device can schedule a post package repair for the address of the corrected error.

• The electronic device includes a memory module with dynamic random access memory (DRAM).
• The processor in the device can access the memory module and detect corrected errors when reading data.
• The device can determine the corrected error count associated with the address of the corrected error.
• An error log associated with the corrected error can be read by the processor.
• The device can determine the risk level of the corrected error based on the information in the error log.
• If the risk level is high, the device can schedule a post package repair (PPR) for the address of the corrected error.

Potential Applications:

• This technology can be used in electronic devices that rely on memory modules, such as computers, smartphones, and servers.
• It can be particularly useful in critical systems where data integrity is crucial, such as aerospace and defense applications.

Problems Solved:

• The technology addresses the issue of errors in memory modules by detecting and correcting them.
• It also solves the problem of determining the risk level associated with a corrected error, allowing for appropriate actions to be taken.

Benefits:

• Improved reliability and data integrity in electronic devices.
• Reduced risk of data corruption or loss due to memory errors.
• Efficient scheduling of post package repairs based on the risk level of corrected errors.

Original Abstract Submitted

Disclosed is an electronic device including a memory module that includes at least one dynamic random access memory, and a processor configured to access the memory module, determine a corrected error count associated with an address of a corrected error in response to the corrected error being detected when data are read from the memory module, read an error log associated with the corrected error, determine a risk level of the corrected error based on the error log, and schedule a post package repair (PPR) for the address of the corrected error in response to the risk level of the corrected error being high.
