Abstract

The invention provides a capacitor electric leakage detection method and device, equipment and a medium, and relates to the technical field of storage. The method comprises the steps that first change correlation information of capacitance retention time of a to-be-detected storage capacitor and word line voltage of a to-be-detected word line is obtained, the word line voltage of the to-be-detected word line changes in a preset voltage range including word line closing voltage, and when the first change correlation information meets a first anomaly judgment condition, the to-be-detected storage capacitor is detected according to the first anomaly judgment condition; determining that the electric leakage behavior of the to-be-detected storage capacitor is related to the to-be-detected word line; or second change correlation information of capacitance retention time of the to-be-detected storage capacitor and word line voltage of an adjacent word line is obtained, the word line voltage of the adjacent word line changes in a preset voltage range, and under the condition that the second change correlation information meets a second anomaly judgment condition, the to-be-detected storage capacitor is detected. And determining that the electric leakage behavior of the to-be-detected storage capacitor is related to the adjacent word line. According to the embodiment of the invention, fine detection of the electric leakage behavior of the capacitor can be realized.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular, to a method, device, device, and medium for detecting capacitance leakage of a memory cell array. Background technique [0002] In the field of storage technology, the leakage of the storage capacitor often affects the performance of the memory. Therefore, how to detect the leakage current of the capacitor has become an urgent problem to be solved. [0003] The current leakage detection technology of the storage capacitor can realize the rough detection of whether the storage capacitor has leakage, but cannot realize the fine detection of the specific leakage position of the leakage behavior of the storage capacitor. [0004] It should be noted that the information disclosed in the above Background section is only for enhancing understanding of the background of the application, and therefore may include information that does not form the prior art known to a pers...
