Abstract: Example implementations relate to memory read requests. For example, an implementation may include tracking progress of an iterative write sequence to write data to a memory element of a memory module. A received read request is detected to be addressed to a memory bank that includes the memory element undergoing the iterative write sequence. Based on the tracked progress, a time is determined to interrupt the iterative write sequence with insertion of the read request. The time aligns between operations of the iterative write sequence and data is returned within a predetermined read latency.

Abstract: The present disclosure provides a data storage device that includes a memory cell array and sense circuitry to detect a data value stored to a memory cell of the memory cell array. The data storage device also includes a controller to bias the sense circuitry during a read phase of a write operation to increase the probability that the sense circuitry will detect an opposite value that, is opposite from the value being written to the memory cell.

Abstract: A method for managing data using a number of non-volatile memory arrays is described. The method includes writing data from a volatile memory region to a first non-volatile memory array. The method also includes writing a remaining portion of the data from the volatile memory region to a second non-volatile memory array in response to detecting that an event has occurred. The second non-volatile memory array has a lower write latency than the first non-volatile memory array.

Abstract: A method for managing a multi-lane serial link is described. The method includes establishing a serial link between a number of integrated circuits across a first number of lanes. The first number of lanes are a subset of a number of available lanes on the serial link. The method also includes selecting to change a transmission state of a second number of lanes. The second number of lanes are a subset of the available lanes. The method also includes changing the transmission state of the second number of lanes while transmitting data on a number of remaining lanes. The method further includes synchronizing the first number of lanes and the second number of lanes.

Abstract: Systems and methods are provided for enabling coexistence of Information Technology (IT) systems and Operational Technology (OT) systems, where advanced computing functionality realized by the IT systems can be applied to legacy applications and incumbent hardware technologies resident in the OT systems. A distributed control node (DCN) implemented between the IT and OT systems may comprise a microcontroller system partitioned into two processor clusters. Microservices associated with the IT systems are provisioned to a high performance processor cluster, and legacy applications running bare metal associated with the OT systems are provisioned to a real-time processor cluster. Partitioning of the microcontroller system allows for interoperability between the microservices and the legacy applications.

Abstract: A circuit includes a resistive memory cell in a memory array to store a memory state for the resistive memory cell. A reference cell in the memory array stores a reference memory state for the resistive memory cell. A function generator concurrently applies a read voltage to the resistive memory cell and the reference cell via a memory row address. A sensing circuit enables the function generator and monitors a target current received from the resistive memory cell when selected via a memory column address and monitors a reference current received when selected via a reference column address in response to the read voltage applied to the memory row address. A current comparator circuit in the sensing circuit compares a difference between the target current and the reference current to determine the memory state of the resistive memory cell.
