Claim 0:
1. A test method for a control chip, the control chip comprising a built-in self-test (BIST) circuit, and the test method being performed by the BIST circuit, wherein the test method comprises:
acquiring a current status of a memory chip in a storage device;
using the memory chip in an idle state as a first target memory chip when the current status of the memory chip is the idle state, to store at least some of test vectors used for testing the control chip as first test vectors in the first target memory chip, wherein the idle state is a status of the memory chip when the memory chip currently has not stored any data;
reading the first test vectors stored in the 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.
