Latest Patents

One of Jiho Kim's latest patents involves semiconductor memory devices with error correction. This memory system includes a semiconductor memory device and a memory controller designed to manage the memory device. The semiconductor memory device features a memory cell array divided into multiple sub-array blocks arranged in both a first and second direction. The memory controller is equipped with an error correction code (ECC) engine that generates parity data during write operations. This process involves performing ECC encoding on user data, which consists of several sub-data units. The ECC engine interleaves these sub-data units based on mapping information, ensuring that two sub-data units stored in one row of a target sub-array block are included in a single symbol.

Another notable patent pertains to memory controllers and memory systems. This memory controller includes a processor and is configured to manage a memory module comprising multiple data chips and at least one parity chip. The ECC engine within the controller features an ECC decoder capable of correcting Q symbols errors in a codeword set read from the memory module. The ECC decoder generates a syndrome based on the read codeword set and performs ECC decoding to correct single symbol errors effectively.
