Data Protection Operation
Page programming and Block Erasing can be locked by programming a nonvolatile lock bit for each block.
When
WP
is V
IL
level, those locked blocks as reflected by the Block-Lock Status bits, are protected from
inadvertent Page programming or Block Erasing.
Programmed block data and Lock-Bit Data can be locked When
WP
is V
IL
level.
