2. Applicable when 4M, 8M or 16M Partial Power-Down mode is programmed
3. Some data might be written into any address location if tEHWL (min) is not satisfied.
4. The Input Transition Time (t ) at AC testing is 5ns as shown below. If actual t is longer than 5ns, it may violate AC specification
1. All address inputs must be High from Cycle 1 to Cycle 5.
2. PDCADD stands for Power-Down Configuration Address. It must be compliant with the format specified in Table
