  • Patent number: 10379754
    Abstract: 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.

  • Patent number: 9442842
    Abstract: 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.
