Latest Patents

One of Schmidt's key patents is titled "Dynamic memory with error correction on refresh." This invention discloses an apparatus designed for error correction during the refresh cycle of dynamic memory. The apparatus includes a refresh counter that supplies row addresses to the dynamic memory during refresh cycles. It also features decoder circuitry that provides row address and column address strobe signals to the memory, enabling it to refresh rows sequentially and select one word from each refreshed row for error correction. Additionally, the patent describes a computer system that utilizes semiconductor memory with on-board error correcting circuitry employing Hamming codes to generate check bits. These check bits are crucial for locating and correcting single-bit errors and detecting some double-bit errors. The CPU integrated into this system incorporates a spot check system stored in non-volatile memory, which independently generates syndrome bits from accessed data and compares them to the stored check bits. If discrepancies are found, the CPU halts operations to prevent data corruption.
