Title: Chihjen Chang: Innovator in Non-Volatile Memory Technologies
Introduction
Chihjen Chang is a notable inventor based in Fremont, CA, with a focus on advancements in non-volatile memory technologies. He holds a total of 4 patents, showcasing his contributions to the field of memory modules and data communication protocols.
Latest Patents
One of his latest patents is titled "DIMM SSD Addressing Performance Techniques." This invention discloses a Non-Volatile Dual In-Line Memory Module (NVDIMM) that can be installed in a Dual In-Line Memory Module (DIMM) socket. The NVDIMM includes a non-volatile memory, and a device driver intercepts requests for memory addresses destined for a host memory controller. It replaces the memory address with a pre-mapped memory address or an alias, allowing the host memory controller to generate a target memory address for the NVDIMM.
Another significant patent is the "XOR-Based Scrambler/Descrambler for SSD Communication Protocols." This invention includes methods for descrambling and scrambling a memory channel. It executes a training mode for the memory device to discover XOR vectors used by the host system to scramble data. The training mode inputs all-zero training data to a scrambling algorithm, generating scrambled training data that is transmitted over the memory channel to the memory device. The scrambled training data is stored as XOR vectors for each corresponding memory location, which are then used during functional mode to descramble data prior to writing.
