Patent number: 10031676Abstract: In a memory controller, a request handler processes a write request which is issued from a CPU and requests data write to a memory device using a phase change memory, and a request queue stores the write request. A scheduler returns a completion on the write request to the CPU when a predetermined write time has elapsed. The predetermined write time is shorter than a write latency time that is taken to complete the data write to a memory cell of the memory device in response to the write request.Type: GrantFiled: July 13, 2016Date of Patent: July 24, 2018Assignees: MEMRAY CORPORATION, YONSEI UNIVERSITY, UNIVERSITY—INDUSTRY FOUNDATION (UIF)Inventors: Jaesoo Lee, Myoungsoo Jung, Gyuyoung Park

Publication number: 20170352403Abstract: A memory controller of a memory device that uses a phase change memory and includes a memory cell array partitioned into a plurality of partitions is provided. A write request that request a data write to the memory device and a read request which request a data read from the memory device are inserted to a request queue. A scheduler, in a case that a conflict check condition including a first condition that a write operation is being performed in a first partition among the plurality of partitions is satisfied, creates a read command for a second partition based on a read request for the second partition when the request queue includes the read request for the second partition. The second partition is a partition, in which a read operation does not conflict with the write operation in the first partition, among the plurality of partitions.Type: ApplicationFiled: July 20, 2016Publication date: December 7, 2017Inventors: Jaesoo LEE, Myoungsoo JUNG, Gyuyoung PARK

Patent number: 8904072Abstract: A storage system includes a first device having a device manager, and a storage device to generate a domain with the first device. The storage device further includes a domain manager that sends a domain manager message to the first device in response to a discovery message transferred from the device manager. The device manager may register the first device in the domain based on a registration device message transferred according to the domain manager message, and may notify components of the first device. The registered components of the first device are deployed as components of an application program to process data stored in a storage media of the storage device such that a function of the storage device is dynamically extended.Type: GrantFiled: December 21, 2011Date of Patent: December 2, 2014Assignee: SAMSUNG Electronics Co., Ltd.Inventor: Jaesoo Lee
