68 / 78 page Extended Memory Block M29W128FH, M29W128FL 68/78 C.2 Customer Lockable Extended Memory Block A device where the Extended Memory Block is customer lockable is delivered with the DQ7 bit set to ‘0’ and the Extended Memory Block unprotected. It is up to the customer to program and protect the Extended Memory Block but care must be taken because the protection of the Extended Memory Block is not reversible. There are two ways of protecting the Extended Memory Block: ● Issue the Enter Extended Block command to place the device in Extended Block mode, then use the In-System Technique with RP either at VIH or at VID (refer to Appendix D: High Voltage Block Protection, and to the corresponding flowcharts, Figure 20 and Figure 21, for a detailed explanation of the technique). ● Issue the Enter Extended Block command to place the device in Extended Block mode, then use the Programmer Technique (refer to Appendix D: High Voltage Block Protection, and to the corresponding flowcharts, Figure 18 and Figure 19, for a detailed explanation of the technique). Once the Extended Memory Block is programmed and protected, the Exit Extended Block command must be issued to exit the Extended Memory Block mode and return the device to Read mode. Table 35.
