Notes: 1. R = Read-only
R/W = One-time programmable and readable
R/W/E = Multiple writable with the value kept after a power cycle, assertion of the
RST_n signal, and any CMD0 reset, and readable
R/W/C_P = Writable after the value is cleared by a power cycle and assertion of the
RST_n signal (the value not cleared by CMD0 reset) and readable
R/W/E_P = Multiple writable with the value reset after a power cycle, assertion of the
RST_n signal, and any CMD0 reset, and readable
W/E_P = Multiple writable with the value reset after power cycle, assertion of the RST_n
signal, and any CMD0 reset, and not readable
TBD = To be determined
2. Reserved bits should be read as 0.
3. Micron has tested power failure under best application knowledge conditions with posi-
tive results. Customers may request a dedicated test for their specific application condi-
tion.
4. Set at 00h when shipped for optimized write performance; can be set to 1Fh to enable
protection on previously written data if power failure occurs during a WRITE operation.
This byte is one-time programmable.
