Patent number: 11899942Abstract: Examples of systems and method described herein provide for accessing memory devices and, concurrently, generating access codes using an authenticated stream cipher at a memory controller. For example, a memory controller may use a memory access request to, concurrently, perform translation logic and/or error correction on data associated with the memory access request; while also utilizing the memory address as an initialization vector for an authenticated stream cipher to generate an access code. The error correction may be performed subsequent to address translation for a write operation (or prior to address translation for a read operation) to improve processing speed of memory access requests at a memory controller; while the memory controller also generates the encrypted access code.Type: GrantFiled: December 23, 2022Date of Patent: February 13, 2024Assignee: Micron Technology, Inc.Inventors: Jeremy Chritz, David Hulton

Patent number: 11870513Abstract: Examples described herein include systems and methods, including wireless devices and systems with neuron calculators that may perform one or more functionalities of a wireless transceiver. The neuron calculator calculates output signals that may be implemented, for example, using accumulation units that sum the multiplicative processing results of ordered sets from ordered neurons with connection weights for each connection between an ordered neuron and outputs of the neuron calculator. The ordered sets may be a combination of some input signals, with the number of signals determined by an order of the neuron. Accordingly, a kth-order neuron may include an ordered set comprising product values of k input signals, where the input signals are selected from a set of k-combinations with repetition. As an example in a wireless transceiver, the neuron calculator may perform channel estimation as a channel estimation processing component of the receiver portion of a wireless transceiver.Type: GrantFiled: June 29, 2021Date of Patent: January 9, 2024Assignee: Micron Technology, Inc.Inventors: Fa-Long Luo, Jaime Cummins, Tamara Schmitz, Jeremy Chritz

Publication number: 20230410873Abstract: Methods and apparatus for utilizing non-traditional (e.g., probabilistic or statistically-based) refresh schemes in non-volatile memory. In one embodiment, the memory is characterized in terms of its performance, such as based on BER (bit error rate) as a function of refresh rate based on statistical data for decay of capacitance within the cells of the device with time. In one variant, error-tolerant applications make use of the non-traditionally refreshed (or unrefreshed) memory with enhanced memory bandwidth, since refresh operations have been reduced or eliminated. In another variant, an extant refresh scheme is modified based on a specified minimum allowable performance level for the memory device, In yet another embodiment, error-intolerant applications operate the memory with a reduced or eliminated refresh, and cells or regions of the memory not adequately refreshed by presumed random read/write operations of the memory over time are actively refreshed.Type: ApplicationFiled: August 25, 2023Publication date: December 21, 2023Inventors: David Hulton, Jeremy Chritz, Jonathan D.

Publication number: 20230394143Abstract: Methods, systems, and devices for protective actions for a memory device based on detecting an attack are described. In some systems, a memory device may detect whether a fault is injected into the memory device. The memory device may apply a delay during boot up if a fault is detected. To ensure the delay is applied, the memory device may default to applying the delay and may remove an indication to apply the delay if a fault is not detected. Additionally or alternatively, the memory device may erase information from non-volatile memory during boot up, for example, if a fault is detected. The memory device may be configured to ensure at least a specific portion of memory resources (e.g., resources configured to store sensitive information) is erased during boot up. In some examples, the memory device may store data using a stream cipher to improve security of the data.Type: ApplicationFiled: January 31, 2023Publication date: December 7, 2023Inventors: Aaron P.

Publication number: 20230334152Abstract: Methods, systems, and devices for temperature change measurement to detect an attack on a memory device are described. A memory device may measure a rate of change for temperature readings at a dynamic random access memory (DRAM) component of the memory device (e.g., using sensors at the DRAM component). The memory device may compare the rate of change for the temperature to a threshold, for example, using circuitry, a threshold value stored in memory, or both. If the memory device determines that the rate of change for the temperature satisfies the threshold, the memory device may disable one or more features of the memory device to protect against a potential attack. For example, an attack on the memory device may be indicated by the change in temperature readings at the DRAM component, and the memory device may perform one or more protective measures based on detecting the temperature change.Type: ApplicationFiled: April 15, 2022Publication date: October 19, 2023Inventors: Aaron P.
