Advanced Sector Protection/Unprotection The Advanced Sector Protection/Unprotection feature disables or enables programming or erase operations in any or all sectors and can be implemented through software and/or hardware methods, which are independent of each other. This section describes the various methods of protecting data stored in the memory array. An overview of these methods in shown in Figure 8.1. Figure 8.1 Advanced Sector Protection/Unprotection Hardware Methods Software Methods WP#/ACC = VIL (Highest or Lowest Sector Locked) Password Method (DQ2) Persistent Method (DQ1) Lock Register (One Time Programmable) PPB Lock Bit 1,2,3 64-bit Password (One Time Protect) 1 = PPBs Unlocked 0 = PPBs Locked Memory Array Sector 0 Sector 1 Sector 2 Sector N-2 Sector N-1 Sector N 3 PPB 0 PPB 1 PPB 2 PPB N-2 PPB N-1 PPB N Persistent Protection Bit (PPB) 4,5 DYB 0 DYB 1 DYB 2 DYB N-2 DYB N-1 DYB N Dynamic Protection Bit (DYB) 6,7,8 7. 0 = Sector Protected, 1 = Sector Unprotected. 8. Protect effective only if PPB Lock Bit is unlocked and corresponding PPB is “1” (unprotected). 9. Volatile Bits: defaults to user choice upon power-up (see ordering options). 5. 0 = Sector Protected, 1 = Sector Unprotected. 6. PPBs programmed individually, but cleared collectively 1. Bit is volatile, and defaults to “1” on reset. 2. Programming to “0” locks all PPBs to their current state. 3. Once programmed to “0”, requires hardware reset to unlock. 4. N = Highest Address Sector. |
