RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin that indicates whether an Em-
bedded Algorithm is in progress or complete. The RY/BY# status is valid after the
rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an
open-drain output, several RY/BY# pins can be tied together in parallel with a
pull-up resistor to V
CC

Notes:
1. VA = Valid address for programming. During a sector
erase operation, a valid address is an address within
any sector selected for erasure. During chip erase, a
valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 =
1
because
DQ7 may change simultaneously with DQ5.
