Redundant Data Error Correction TRIZ Cases
- Memory Cell Array Unit Defect Handling via Bit Allocation
Microcontroller redirects n-1 bit write data to healthy cells, avoiding large defect tables and decoding failures.
- Integrated I/O Lockstep Processing for ASIL-D Safety
Merging two I/O stacks into one CPU reduces device complexity while maintaining high reliability for ADAS applications.
- Command Address Bus Timing Margin Training for Memory Modules
Parity-based training commands measure setup and hold margins on backside bus segments to prevent silent data corruption at high frequencies.
- MCU Memory Fault Detection via Interface Circuit Check Words
Interface circuits calculate check words to detect memory errors without processor intervention, resolving delays in triggering power stop procedures.
- Memory System RAID Recovery ECC Failure Migration
Detects ECC failures in memory cell regions and migrates recovered data to secondary regions, reducing frequent read operations that shorten system lifespan.
- Register Bank Scan Chain for SEU Detection and Restoration
A register bank uses a scan chain arrangement to shift parameters sequentially for integrity verification.
