For purposes of IDD testing, the following parameters are to be utilized
Detailed IDD7
The detailed timings are shown below for IDD7. Changes will be required if timing parameter changes are made to the specification.
Legend: A = Active; RA = Read with Autoprecharge; D = Deselect
IDD7: Operating Current: All Bank Interleave Read operation
All banks are being interleaved at minimum tRC(IDD) without violating tRRD(IDD) using a burst length of 4. Control and address bus
inputs are STABLE during DESELECTs. IOUT = 0mA
