Notes:
ADDRESS
22. In this depth expansion example, B1 represents Bank #1 and B2 is Bank #2; Each bank consists of one QuadPort DSE device from this data sheet.
23. LB = UB = OE = CNTLD = V
24. Output state (HIGH, LOW, or high-impedance) is determined by the previous cycle control signals.
25. LB = UB = CNTLD = V
26. Addresses do not have to be accessed sequentially since CNTLD = V
27. During “No Operation,” data in memory at the selected address may be corrupted and should be rewritten to ensure data integrity.
