Abstract: A memory device and its manufacturing method are provided. Memory cells of the memory device arranged in an array respectively include an access transistor and a storage capacitor connected to the access transistor through a capacitor contact (CC) structure. Based on a specific arrangement manner, the CC structures are closely arranged in pairs. Each pair of the CC structures are connected to a neighboring access transistor and isolated from each other through an isolation wall. Each isolation wall includes an inner wall and outer walls located on opposite sides of the inner wall. The inner wall has sufficient etch selectivity with respect to the outer walls. Despite etchants or reactive substances inevitably consume the outer walls during manufacturing, the etchants or the reactive substances may be blocked by the inner wall without penetrating the entire isolation wall. Therefore, an electrical isolation between the neighboring CC structures may be guaranteed.

Abstract: This document relates to employing biosignals to evaluate predictions made by predictive models. For example, user attention can be inferred from a user attention signal such as gaze. When the user directs attention to a prediction output by a given predictive model, a user reaction signal such as an electroencephalogram or pupillary diameter measurement can be processed to determine whether the user perceives an error. If the user perceives an error, an error indication can be output. Error indications can be used to evaluate the predictive model, replace predictions generated by the predictive model, train the predictive model, etc.
