Abstract: Some embodiments of the present application provide a method for registering a fingerprint, a terminal, and a computer readable storage medium. The method for registering a fingerprint includes: acquiring fingerprint images collected in response to a user sliding a finger; filtering the fingerprint images to select filtered images that satisfy a preset filtering condition; and registering the filtered images into a fingerprint template. Thus, the user can register the fingerprint by sliding the finger, without pressing a number of times, which improves user experience and helps to enhance identification performance.

Abstract: The disclosure provides a dual-port static random access memory cell layout structure, including a pull-down transistor layout structure, a first and a second pass transistor layout structure. Each of them includes an active region pattern and a polysilicon pattern; and contact hole patterns. The active region pattern of the pull-down transistor layout structure and the first pass transistor layout structure are connected together, and share the contact hole pattern at one end. The active region pattern of the pull-down transistor layout structure and the second pass transistor layout structure are connected together, and share the contact hole pattern at the other end. The disclosure optimizes the dual-port static random access memory cell layout structure, improves the influence of the optical fillet effect on device matching, strengthens the performance including read-write crosstalk of the pull-down transistor under the situation of the same area, and increases the read current.

Abstract: The present disclosure provides a testing method for reading current of static random access memory, the method comprising: for each basic static random access memory cell, coupling a gate of a first pull-down transistor to a first bit line; setting a word line and the first bit line at a high potential; and sensing current of the first bit line. The testing method provided in the present disclosure can also be applied to static random access memory cells arranged in matrices, so as to efficiently complete the tests for the reading current of the static random access memory in batches.

Abstract: Disclosed are a fingerprint information dynamic updating method and a fingerprint recognition apparatus. The method includes the steps of: collecting fingerprint information, and performing fingerprint recognition according to the collected fingerprint information and a pre-registered fingerprint template database; after the fingerprint recognition succeeds, determining whether the fingerprint template database is saturate; if the fingerprint template database is not saturate and the collected fingerprint information satisfies a first updating condition, adding the collected fingerprint information to the fingerprint template database; and if the fingerprint template database is saturate and the collected fingerprint information satisfies a second updating condition, selecting target fingerprint information from the fingerprint template database, and replacing the target fingerprint information with the collected fingerprint information.
