Abstract
A testing method includes the following steps of: accessing a memory chip to put the memory chip into a write leveling mode; inputting a strobe signal into the memory chip under the write leveling mode; adjusting signal edges of the strobe signal to sample a clock state of a clock signal in the memory chip under the write leveling mode; generating a data signal according to the strobe signal under the write leveling mode; and determining types of the memory chip according to the data signal under the write leveling mode.
Claims20
A testing method, comprising:
- accessing a memory chip to put the memory chip into a write leveling mode;
- inputting a strobe signal into the memory chip under the write leveling mode;
- adjusting signal edges of the strobe signal to sample a clock state of a clock signal in the memory chip under the write leveling mode;
- generating a data signal according to the strobe signal under the write leveling mode;
- and
- determining types of the memory chip according to the data signal under the write leveling mode.
