Hi Dinesh,
Please have a look to the datasheet:
http://www.nxp.com/documents/data_sheet/MF1S50YYX_V1.pdf
You will see that the memory space is divided in sectors and blocks. Each sector has its own so called “sector trailer”. In the sector trailer the access permission including two passwords are set.
If someone has used a sector and protect this sector with one of the passwords, you can read or write only, if you know the password.
Kind regards,
The TapLinx Team
