During this test mode, VDDQ remains within the recommended operating conditions and no timing parameters are ensured. (2) VID is the magnitude of the difference between the input level on CK and the input level on CK, see Figure 10 for definition. The CK and CK VIH and VIL limits define the dc low and high levels for the logic detect state. 5 Submit Documentation Feedback |
