REG: FLASH BLOCK LOCKING

[Ashok M Padmanaban]

Hi,
Are there any methods by which portions of  falsh device can be locked,
so that accidental erase or corruption can be avoided.
If there are, what are those.
Are there any temporary and permanent locking mechanism.

In 3 volt intel strataFlash memory 28F128J3A, a block locking
scheme is provided with BLOCK LOCK-BITS.
How can these bits be used to lock the flash blocks.?
If  blocks are locked , does this mean that accross the power cycles
this will be consistent.

regards
ashok
