... M29W640FT, M29W640FB 4 Command Interface All Bus Write operations to the memory are interpreted by the Command Interface. Commands consist of one or more sequential Bus Write operations. Failure to observe a valid sequence of Bus Write operations will result in the memory returning to Read mode. The long command sequences are imposed to maximize data security. ...

... If any selected blocks are protected then these are ignored and all the other selected blocks are erased. If all of the selected blocks are protected the Block Erase operation appears to start but will terminate within about 100µs, leaving the data unchanged. No error condition is given when protected blocks are ignored. 20/72 M29W640FT, M29W640FB (CFI), Tables 22, 23, 24, 25, 26 and 27 for details on Cycles ...
