DESCRIPTION  
The M34C00 is a 384-bit serial EEPROM. The  
bottom third of the memory area (from location 00h  
to 0Fh) can be Write-protected using a specially  
designed software Write-protection mechanism.  
By sending the device a specific sequence, the  
first 128 bits of the memory become permanently  
Write-protected. Care must be taken when using  
this sequence as its effect cannot be reversed.  
The top third of the memory area (from location  
20h to 2Fh) is already configured to give the  
functional equivalence of a non-erasable memory.  
That is, it is initialized to all 1s (FFh), and the user  
is able to reset any number of those 1s to 0; but  
there is no mechanism for the user to set a 0 back  
to a 1.
