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.
