Publication number: 20240020052Abstract: Embodiments of the present disclosure relate to a memory system and an operating method of the memory system. According to embodiments of the present disclosure, the memory system may receive a default enabled information from the host. The default enabled information indicates whether the host maintains a configuration of a host memory buffer in the host and target data stored in the host memory buffer when the memory system is in a low power mode state in which power supplied from the host is cut off.Type: ApplicationFiled: September 27, 2023Publication date: January 18, 2024Inventors: Jeong Hyun KIM, Byong Woo RYU, Ji Hun CHOI, Son Hong MIN, Sung Ju YOO

Publication number: 20230244607Abstract: Provided herein is a memory controller for controlling a memory device. The memory controller includes a workload detector configured to determine a change in workload based on reception of a changed request from a host or a change in clock received from an external device, a device performance controller configured to determine, if the workload is determined as changed, read performance based on a ratio of a size of data output to the host to a size of data requested from the host every preset period and configured to output a read-look-ahead (RLA) command to the memory device based on the determined read performance, a buffer memory configured to store data read from the memory device in response to the RLA command and a memory size controller configured to control a size of the buffer memory. The RLA command instructs to output data which is frequently requested from the host.Type: ApplicationFiled: April 11, 2023Publication date: August 3, 2023Inventors: Na Young LEE, Ku Ik KWON, Kyeong Seok KIM, Byong Woo RYU

Patent number: 11693595Abstract: The present technology provides a method of operating a host communicating with a memory system including a journal area and a data area. The method of operating the host includes determining to update old data stored in the memory system, transferring, to the memory system, a write command for writing journal data and meta journal data for updating the old data to the journal area, and transferring, to the memory system, a write command for writing new data corresponding to the journal data to the data area in response to a write completion of the meta journal data and the journal data received from the memory system. Each of the meta journal data and the journal data includes a descriptor identifier (ID) indicating the same write transaction.Type: GrantFiled: July 13, 2021Date of Patent: July 4, 2023Assignee: SK hynix Inc.Inventors: Chul Woo Lee, Jeong Hyun Kim, Byong Woo Ryu, Min Su Son, Na Young Lee
