Patent number: 10410686Abstract: A memory module includes semiconductor memory devices, a power management integrated circuit (PMIC), and a control device. The semiconductor memory devices, mounted on a circuit board, operate based on a power supply voltage. The PMIC, mounted on the circuit board, generates the power supply voltage, provides the power supply voltage to the semiconductor memory devices, and stores a trimming control code associated with a minimum level of the power supply voltage when the semiconductor memory devices operate normally in a test mode. During the test mode, the PMIC adjusts a level of the power supply voltage, tests the semiconductor memory devices using the adjusted power supply voltage, and stores the trimming control code based on a result of the test. The control device controls the PMIC based on a first control signal received from an external device.Type: GrantFiled: April 18, 2018Date of Patent: September 10, 2019Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hwan-Wook Park, Yong-Jin Kim, Jin-Seong Yun, Kyu-Dong Lee

Publication number: 20140096931Abstract: A heat radiating pipe (2) that is disposed in a hot water mat (1) is extended from the hot water mat (1) to provide an extended portion that is used as connecting pipes (2a and 2b) to a heat source machine (11). The construction makes it possible to prevent a water leak as there is no connection therebetween, and reduces costs for parts and installation as no connection tool, such as a coupler, is used. Further, guide pieces (13 and 14) attached with cover members (17) are arranged at positions where the connecting pipes (2a and 2b) are extended, and the connecting pipes (2a and 2b) are disposed by using the guide pieces (13 and 14), so as to efficiently utilize heat radiated from the connecting pipes (2a and 2b), and to prevent thermal loss.Type: ApplicationFiled: October 7, 2013Publication date: April 10, 2014Applicant: Sumisho Metalex CorporationInventors: Ogawa KEIICHIRO, Kyu Dong LEE
