The detailed timings are shown below for I
conflict with pattern requirements of Table 9, then Table 9 requirements take precedence.
Table 9: I
Timing patterns for 4-bank x4/x8/x16 devices
1. A = active; RA = read auto precharge; D = deselect.
2. All banks are being interleaved at
3. Control and address bus inputs are STABLE during DESELECTs.
