Patent number: 10642681Abstract: A device includes a memory device and a controller. The memory device includes read/write circuitry and a plurality of memory dies. The controller is coupled to the memory device. The controller is configured to, responsive to determining that at least one storage element of a first die of the plurality of memory dies has a characteristic indicative of an aging condition, increase the temperature of the first die by performing memory operations on the first die until detecting a condition related to the temperature.Type: GrantFiled: May 3, 2018Date of Patent: May 5, 2020Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Preeti Yadav, Prasanna Desai Sudhir Rao, Smita Aggarwal, Dana Lee

Patent number: 10379754Abstract: A device includes a memory device and a controller. The controller is coupled to the memory device. The controller is configured to, in response to receiving a request to perform a memory access at the memory device, determine that the memory device has a characteristic indicative of a temperature crossing. The controller is also configured to, in response to determining that the memory device has the characteristic indicative of the temperature crossing, determine that the memory device satisfies an availability criterion. The controller is further configured to, in response to determining that the memory device satisfies the availability criterion, increase a temperature of the memory device by performing memory operations on the memory device until detecting a condition related to the temperature.Type: GrantFiled: January 20, 2018Date of Patent: August 13, 2019Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Philip David Reusswig, Nian Niles Yang, Grishma Shah, Deepak Raghu, Preeti Yadav, Prasanna Desai Sudhir Rao, Smita Aggarwal, Dana Lee

Patent number: 9442842Abstract: A nonvolatile memory die is tested to determine certain parameters such as read time, which are then recorded in the nonvolatile memory die. After the die is incorporated into a memory system, and firmware is downloaded, the nonvolatile memory system uses the recorded parameters to determine how to configure the memory system for operation within specified limits, such as determining how much delay to apply to read operations.Type: GrantFiled: August 19, 2013Date of Patent: September 13, 2016Assignee: SanDisk Technologies LLCInventors: Preeti Yadav, Barys Sarana, Abhijeet Bhalerao, Frederick Fernandez, Namita Joshi
