Hardware protection
The M29W128GH and M29W128GL feature a V
lowest block. Refer to
Software protection
The M29W128GH and M29W128GL have three different software protection modes:
On first use all parts default to operate in non-volatile protection mode and the customer is
free to activate the non-volatile or the password protection mode.
The desired protection mode is activated by setting either the one-time programmable non-
volatile protection mode lock bit, or the password protection mode lock bit of the lock
register (see
bit or the password protection mode lock bit, to ‘0’ will permanently activate the non-volatile
or the password protection mode, respectively. These two bits are one-time programmable
and non-volatile: once the protection mode has been programmed, it cannot be changed
and the device will permanently operate in the selected protection mode. It is recommended
to activate the desired software protection mode when first programming the device.
The non-volatile and password protection modes both provide non-volatile protection.
Volatilely protected blocks and non-volatilely protected blocks can co-exist within the
memory array. However, the volatile protection only control the protection scheme for blocks
that are not protected using the non-volatile or password protection.
If the user attempts to program or erase a protected block, the device ignores the command
and returns to read mode.
The device is shipped with all blocks unprotected. The block protection status can be read
either by performing a read electronic signature (see
Auto Select command (see
For the lowest and highest blocks, an even higher level of block protection can be achieved
by locking the blocks using the non-volatile protection and then by holding the V
