Function Description
Status Register: The HN29V25611A outputs the operation status data as follows: I/O7 pin outputs a V
indicate that the memory is in either erase or program operation. The level of I/O7 pin turns to a V
the operation finishes. I/O5 and I/O4 pins output V
complete in a finite time, respectively. If these pins output V
out. If I/O6 pin outputs V
ECC or not by reading out the data. When these pins monitor, I/O7 pin must turn to a V
erase and program operation, the status data must be cleared after a time out occurs. From I/O0 to I/O3 pins
are reserved for future use. The pins output V
The function of the status register is summarized in the following table.

ECC Applicability
This device needs to be corrected failure data by ECC on system or Spare sectors, by reading out again the
failure sector data when program/erase error occures.
