Patent number: 8908464Abstract: Systems and methods for detecting power attacks related to subnormal read voltage on an integrated circuit. Upon initiating power up of the integrated circuit and prior to reading configuration information from non-volatile memory (NVM), test cells associated with the NVM are read first. The test cells share a common power supply with the NVM and output read values from the test cells are configured to deviate from values pre-programmed in the test cells when a subnormal read voltage is applied on the common power supply. Thus, by comparing the output read values with the pre-programmed values, it can be determined whether voltage of the common power supply is subnormal, wherein configuration information will be read incorrectly at a subnormal read voltage. If the voltage is subnormal, power up is aborted. Otherwise, power up is allowed to proceed by reading the configuration information from the NVM.Type: GrantFiled: February 12, 2013Date of Patent: December 9, 2014Assignee: QUALCOMM IncorporatedInventors: Gregory Ameriada Uvieghara, Michael Batenburg, Esin Terzioglu, Yucong Tao

Patent number: 8867304Abstract: A technique for memory command throttling in a partitioned memory subsystem includes accepting, by a master memory controller included in multiple memory controllers, a synchronization command. The synchronization command includes command data that includes an associated synchronization indication (e.g., synchronization bit(s)) for each of the multiple memory controllers and each of the multiple memory controllers controls a respective partition of the partitioned memory subsystem. In response to receiving the synchronization command, the master memory controller forwards the synchronization command to the multiple memory controllers. In response to receiving the forwarded synchronization command each of the multiple memory controllers de-asserts an associated status bit. In response to receiving the forwarded synchronization command, each of the multiple memory controllers determines whether the associated synchronization indication is asserted.Type: GrantFiled: June 6, 2013Date of Patent: October 21, 2014Assignee: International Business Machines CorporationInventors: John Dodson, Karthick Rajamani, Eric Retter, Kenneth Wright
