... Read mode where it can be read in the same way as a ROM or EPROM. The M29W200B is fully backward compatible with the M29W200. The memory is divided into blocks that can be erased independently possible to preserve valid data while old data is erased. Each block can be protected independently to prevent accidental Program or Erase commands from modifying the memory ...

... These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant qual- ity documents. ...

... Once the Unlock Bypass command has been is- sued the memory will only accept the Unlock By- pass Program command and the Unlock Bypass Reset command. The memory can be read Read mode. Unlock Bypass Program Command. The lock Bypass Program command can be used to program one address in memory at a time ...
