Patent number: 11956348Abstract: A method for managing security keys for an I/O device may include loading a first security key from a primary memory to a security engine, performing a first data transfer operation between a host and the I/O device using the first security key with the security engine, loading a second security key from a secondary memory to the security engine, and performing a second data transfer operation between the host and the I/O device using the second security key with the security engine. The method may further include storing the first security key in the primary memory based on a frequency of use of the first security key. The frequency of use of the first security key may be determined by a pattern of transfers between the host and the I/O device.Type: GrantFiled: December 15, 2020Date of Patent: April 9, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Pyeongwoo Lee, Sumanth Jannyavula Venkata, Young Deok Kim

Patent number: 11940861Abstract: Inventive aspects include a device including storage media. The device includes a PMU, and a controller communicatively coupled to the PMU. The PMU determines that an operating power of the device exceeds a threshold, and transmits a signal to the controller to trigger a power reduction operation. The controller throttles one or more operations until the operating power goes below the threshold. Some embodiments include a method for controlling performance of a storage device. The method includes measuring, by a PMU, a power consumption associated with a storage device. The method includes determining, by the PMU, whether the power consumption is greater than a threshold. In response, the method may include setting a performance throttle. The method may include determining, by the PMU, whether the power consumption is less than the threshold. In response, the method may include releasing the performance throttle.Type: GrantFiled: April 21, 2022Date of Patent: March 26, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Young deok Kim, Pyeongwoo Lee, Sumanth Jannyavula Venkata
