Latest Patents
Fujishiro's latest patents include innovative apparatuses, systems, and methods for error correction. These inventions involve memory devices that consist of multiple memory cells, each storing a bit of information. A first latch is designed to hold the encoded bit and provide it as a write parity bit to the memory array during write operations. Additionally, a second latch retains a parity bit read from the memory array, allowing the ECC circuit to generate a command signal based on that parity bit. A multiplexer latch is also utilized to hold the encoded bit and provide a syndrome bit based on the command signal and the encoded bit. This syndrome bit indicates any mismatch between the parity bit and the encoded bit, with the logic for generating the syndrome bit being separated from the logic tree.
