Latest Patents
One of his latest patents is titled "Memory controller having automatic RAM detection." This invention presents a system and method for automatically detecting the presence and configuration of writable memory modules. The process involves writing a first data pattern to a memory location and subsequently writing different data patterns to other locations in a walking-one sequence. The system reads the data pattern at the first memory location and compares it to the original to determine if it has been overwritten. This method ensures efficient memory management and detection.
Another significant patent is the "Method and apparatus for effecting multiple error correction in a memory system." This invention provides a robust method for error detection and correction by dividing large data words into multiple error correction zones. Each zone is combined to form an error domain, allowing for effective error correction capabilities. The method enhances performance by processing error correction code in parallel for multiple domains during read and write operations.
