Abstract
Embodiments of the present disclosure provide a test method and apparatus for a control chip, an electronic device, relating to the field of semiconductor device test technology. The method includes: reading first test vectors stored in a first target memory chip; sending the first test vectors to the control chip; receiving first output information returned by the control chip in response to the first test vectors; and acquiring a first test result of the control chip based on the first output information and the first test vectors corresponding to the first output information. By means of the technical solutions provided in the embodiments of the present disclosure, a memory chip can be used for storing test vectors for a control chip, so that a storage space for test vectors can be enlarged, and the test efficiency can be increased.
