MemRay and Korea Advanced Institute of Science and Technology Assigned Patent

MemRay Corporation, Gyeonggi-do, Korea, and Korea Advanced Institute of Science and Technology, Daejeon, Korea, has been assigned a patent (11775452) developed by Jung, Myoungsoo, Daejeon, Korea, for “non-volatile memory controller device and non-volatile memory device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “In a non-volatile memory controlling device, a first doorbell region is exposed to a configuration space of a host interface and updated when the host issues an input/output (I/O) request command to the host memory. A fetch managing module fetches the command from the host memory in response to an event signal generated when the first doorbell region is updated. A data transferring module checks a location of the host memory based on request information included in the command, and performs a transfer of target data for the I/O request between the host memory and the non-volatile memory module. A completion handling module writes a completion request in the host memory and handles an interrupt when the data transferring module completes to process the I/O request. A second doorbell region is exposed to the configuration space and updated when the I/O service is terminated by the host.”

The patent application was filed on 2021-07-22 (17/382895).
