Abstract: System and method for sharing a PCIe endpoint device with a plurality of host computers, by allocating a quantum of time to a host computer of a plurality of host computers coupled to a PCIe switch, wherein the quantum of time identifies a duration of time during which the host computer has exclusive access to a shareable PCIe endpoint device coupled to the PCIe switch. Requests from the host computer are transmitted to an emulated PCIe endpoint device of the PCIe switch during the quantum of time and the requests are then redirected from the emulated PCIe endpoint device to the shareable PCIe endpoint device during the quantum of time allocated to the host computer.

Abstract: A method for reading a flash memory device includes storing configuration files of reliability-state Classification Neural Network (CNN) models and Regression Neural Network (RNN) inference models, and storing reliability-state tags corresponding to reliability states. The current number of P/E cycles is identified and a reliability-state CNN model is selected corresponding to the current number of P/E cycles. A neural network operation of the selected reliability-state CNN model is performed to identify a predicted reliability state. Corresponding reliability-state tags are identified and a corresponding RNN inference model is selected. A neural network operation of the selected RNN inference model is performed, using the reliability-state tags as input, to generate output indicating the shape of a threshold-voltage-shift read-error (TVS-RE) curve. Threshold Voltage Shift Offset (TVSO) values are identified corresponding to a minimum value of the TVS-RE curve and a read is performed using a threshold-voltage-shift read at the identified TVSO values.

Abstract: A packaged electronic die having a micro-cavity and a method for forming a packaged electronic die. The packaged electronic die includes a photoresist frame secured to the electronic die and extending completely around the device. The photoresist frame is further secured to a first major surface of a substrate so as to form an enclosure around the device. Encapsulant material extends over the electronic die and around the sides of the electronic die. The encapsulant material is in contact with the first major surface of the substrate around the entire periphery of the electronic die so as to form a seal around the electronic die.
