Legend
X = Don’t care.
RA = Address of the memory location to be read.
SA = Sector Address. Any address that falls within a specified sector. See Table 8.2 on page 14 and Table 8.3 on page 20 for sector address ranges.
PWA = Password Address. Address bits A1 and A0 are used to select each 16-bit portion of the 64-bit entity.
PWD = Password Data.
RD(0) = DQ0 protection indicator bit. If protected, DQ0 = 0. If unprotected, DQ0 = 1.
Notes
1. All values are in hexadecimal.
2. Shaded cells indicate read cycles.
3. Address and data bits not specified in table, legend, or notes are don’t cares (each hex digit implies 4 bits of data).
4. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. The system must write the reset
command to return the device to reading array data.
5. Entry commands are required to enter a specific mode to enable instructions only available within that mode.
6. No unlock or command cycles required when bank is reading array data.
7. Exit command must be issued to reset the device into read mode; device may otherwise be placed in an unknown state.
8. Entire two bus-cycle sequence must be entered for each portion of the password.
9. Full address range is required for reading password.
10. Password may be unlocked or read in any order. Unlocking requires the full password (all seven cycles).
11. ACC must be at VIH when setting PPB or DYB.
12. “All PPB Erase” command pre-programs all PPBs before erasure to prevent over-erasure.
