AC Characteristics
Address boundary occurs every 64 words, beginning at address
00003Fh: (00007Fh, 0000BFh, etc.) Address 000000h is also a boundary crossing.

Notes:
1. RDY active with data (A18 = 0 in the Configuration Register).
2. RDY active one clock cycle before data (A18 = 1 in the Configuration Register).
3. Cxx indicates the clock that triggers Dxx on the outputs; for example, C60 triggers D60. Figure shows the device
crossing a bank in the process of performing an erase or program.
