摘要： A memory system is configured to convert multiple programmable memory or a portion thereof to one-time programmable (OTP) memory. The system is configured to repetitively perform memory operations (such as program and erase procedures) on a portion of memory in order to induce accelerated degradation (aging) of select memory cells, thereby permanently changing the select cells, such that a pattern of the cells with degraded performance indicate a data value that has been permanently encoded into the memory.

摘要： A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, a number of errors resulting from the memory operations may be determined, or a number of memory cells storing noisy bits may be identified. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit or defective memory. If so, the logic determines that the memory under test is counterfeit or defective and provides a notification about such determination.

摘要： A random number generation system may generate one or more random numbers based on the repeated programming of a memory, such as a flash memory. As an example, a control system may repeatedly store a sequence to a block of flash memory to force a plurality of cells into a random state such that, at any given instant, the values in the cells may be random. The control system may identify which of the cells contain random values and then generate based on the identified values a number that is truly random.

摘要： A radiation detection system may include a mobile device having a flash memory. The device may monitor various characteristics of the flash memory to determine when damage to the flash memory has occurred from radiation exposure. The device may associate damage to the flash memory with a radiation dose, and determine a level of radiation to which the memory, and thus the device, has been exposed. The device also may determine a length of time and locations where the radiation exposure has occurred. If the device determines that the level of radiation exposure exceeds a threshold associated with a safe level of radiation exposure for a human user, the device may generate an alert to the user.

摘要： Pre-authorized communication services and/or transactions are provided via a plurality of networks in response to a request received from a user to provide at least one of a communication service, a transaction and user account information via a plurality of networks of different types. Prior to processing the request, there is verification of the user's authorization to receive the at least one of the communication service, the transaction, and the user account information, and that an account associated with the user has a sufficient amount currently available for payment of the at least one of the communication service and the transaction. After verification, an authorized account associated with the user is charged in real time as the at least one of the communication service and the transaction is provided.

摘要： A system for improving radiation tolerance of memory senses an amount of radiation exposure and, based on the sensed amount of radiation exposure, determines whether to perform one or more techniques for mitigating the effects of the radiation exposure. As an example, the system may perform a data refresh operation by re-writing data that has been corrupted by radiation, or the system may adjust the reference voltage used to read memory cells. In another example, the system may perform a fault repair operation by re-programming cells that have erroneously transitioned from a program state to an erase state. The system may selectively perform different radiation-mitigation techniques in a tiered approach based on the sensed amount of radiation in order to limit the adverse effects of the more invasive techniques.

摘要： A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, or a number of errors resulting from the memory operations may be counted or otherwise determined. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit memory. If so, the logic determines that the memory under test is counterfeit (e.g., is recycled or counterfeit) and provides a notification about the authenticity of the memory. The logic may also estimate the age of the memory based on the operational parameters.
