Latest Patents

Choi's latest patents focus on advanced semiconductor memory devices with error correction capabilities. One of his inventions involves a memory system that includes a semiconductor memory device and a memory controller. This memory controller is designed to manage the semiconductor memory device effectively. 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 incorporates 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 specific 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 patent by Choi pertains to memory controllers and memory systems. This invention describes a memory controller that manages a memory module comprising data chips and a parity chip. The ECC engine within this controller includes an ECC decoder that performs dual ECC decoding processes. The first decoding corrects symbol errors in a read codeword set, while the second decoding addresses multi-bit errors and detects triple-bit errors simultaneously. The ECC decoder generates a syndrome that includes multiple sub-syndromes, enabling it to correct symbol errors and manage multi-bit errors effectively.
