Informatio n

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 simulta-

neously with DQ5.

Figure 7. Data# Polling Algorithm

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 VCC.
