Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence
has been written with A18=0; device will output RDY with valid data.
1) Address is 3Eh or offset by a multiple of 64 (40h)
2) Address is 3Fh or offset by a multiple of 64 (40h)

Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence
has been written with A18=0; device will output RDY with valid data.
1) Device crosses a page boundary prior to tRCC
.
2) Device neither crosses a page boundary nor latches a new address prior to tRCC
.
