MEMORY DEVICE WITH REDUNDANCY FOR PAGE-BASED REPAIR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17823740 titled 'MEMORY DEVICE WITH REDUNDANCY FOR PAGE-BASED REPAIR
Simplified Explanation
- Apparatus and methods for page-based soft post package repair are disclosed in the patent application. - The technology involves decoding an address to a prime row, a row-based redundant row, or a page-based redundant row based on data stored in a storage element. - A match logic circuit determines if the address corresponds to a defective prime row and generates a match signal. - A decoder selects a redundant row to be accessed instead of a prime row if the match signal indicates that the address data matches defective address data stored in volatile memory. - Page-based redundant rows allow for page-by-page substitution for defective memory, enabling functional portions of memory to continue to be used.
Potential Applications
- Memory repair in electronic devices - Improving reliability and longevity of memory systems
Problems Solved
- Addressing defects in memory rows - Extending the lifespan of memory components
Benefits
- Enhanced memory reliability - Increased longevity of memory systems - Cost-effective repair solutions for memory issues
Original Abstract Submitted
Apparatus and methods for page-based soft post package repair are disclosed. Based on data stored in a storage element, an address may be decoded to a prime row, a row-based redundant row, or a page-based redundant row. A match logic circuit may determine whether the address corresponds to a defective prime row and generate a match signal. A decoder can select a redundant row to be accessed instead of a prime row in response to the match signal indicating that the address data corresponding to the address to be accessed matches defective address data stored in a volatile memory. A page-based redundant row allows for page-by-page substitution for defective memory, allowing functional portions of memory to continue to be used.
