HN29V102414 Series
Function Description
Status Register: The HN29V102414 outputs the operation status data as follows: I/O7 pin outputs a V_OL to
indicate that the memory is in either erase or program operation. The level of I/O7 pin turns to a V_OH when
the operation finishes. I/O5 and I/O4 pins output V_OLs to indicate that the erase and program operations
complete in a finite time, respectively. If these pins output V_OHs, it indicates that these operations have timed
out. If I/O6 pin outputs V _OH, it indicates a possibility that can be corrected by ECC, choose data correction by
ECC or not by reading out the data. When these pins monitor, I/O7 pin must turn to a V_OH. To execute other
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_OLs and should be masked out during the status data read mode.
The function of the status register is summarized in the following table.

V_OH = Ready, V_OL = Busy
I/O6
Program/Erase ECC When I/O7 outputs V_OH, V_OH = ECC available, V_OL = ECC not available.

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.
