FULL DYNAMIC POST-PACKAGE REPAIR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18091163 titled 'FULL DYNAMIC POST-PACKAGE REPAIR
Simplified Explanation:
The memory controller described in the patent application can detect and repair failing regions of memory by migrating data to a buffer, performing repair operations, and then moving the data to a substitute region in the memory.
Key Features and Innovation:
- Controller responds to repair signal for migrating data from failing memory region to buffer.
- Generates command for post-package repair operation of failing region.
- Migrates data from buffer to substitute region in memory.
- Uses read and write migration requests to move data to and from buffer.
- Arbiter employs multiple arbitration rules for different types of requests.
Potential Applications: This technology could be used in various electronic devices that rely on memory controllers, such as computers, smartphones, and servers.
Problems Solved: This technology addresses the issue of failing memory regions in electronic devices, allowing for efficient repair and data migration to ensure continued functionality.
Benefits:
- Improved reliability and performance of memory controllers.
- Extended lifespan of electronic devices.
- Reduced downtime and maintenance costs.
Commercial Applications: The technology could be valuable for manufacturers of electronic devices looking to enhance the reliability and longevity of their products, potentially leading to increased customer satisfaction and brand loyalty.
Prior Art: Readers interested in prior art related to this technology could explore patents and research papers in the field of memory controllers, data migration, and memory repair technologies.
Frequently Updated Research: Researchers in the field of memory management and data storage may have ongoing studies related to the optimization of memory controllers and repair mechanisms.
Questions about Memory Controller Technology: 1. What are the potential implications of using this memory controller technology in data centers? 2. How does this innovation compare to existing methods of memory repair and data migration in electronic devices?
Original Abstract Submitted
A memory controller includes a command queue, an arbiter, and a controller. The controller is responsive to a repair signal for migrating data from a failing region of a memory to a buffer, generating at least one command to perform a post-package repair operation of the failing region, and migrating the data from the buffer to a substitute region of the memory. The controller migrates the data to and from the buffer by providing migration read requests and migration write requests, respectively, to the command queue. The arbiter uses the plurality of arbitration rules for both the read migration requests and the write migration requests, and the read access requests and the write access requests.
