Data# Polling Algorithm

Notes:
1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. 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.

11.2

RY/BY#: Ready/Busy#

The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded 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

.

If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.)
If the output is high (Ready), the device is in the read mode, the standby mode, or one of the banks is in the erase-suspend-read
mode.

Table on page 37

shows the outputs for RY/BY#.

When DQ5 is set to “1”, RY/BY# will be in the BUSY state, or “0”.
