OTP Program (OTPP)
Read OTP Data Bytes (OTPR)
The OTP Program command programs data in the OTP region, which is in a different address space from the
main array data. Refer to,
Program command is the same as the Page Program command, except that the OTP Program command
requires exactly one byte of data; otherwise, the command will be ignored. To program the OTP in bit
granularity, the rest of the bits within the data byte can be set to “1”.
The OTP memory space can be programmed one or more times, provided that the OTP memory space is not
locked (as described in “Locking OTP Regions”). Subsequent OTP programming can be performed only on
the unprogrammed bits (that is, “1” data).
Note: The Write Enable (WREN) command must precede the OTPP command before programming of the
OTP can occur.
The Read OTP Data Bytes command reads data from the OTP region. Refer to
the OTP region. The protocol of the Read OTP Data Bytes command is the same as the Fast Read Data
Bytes command except that it will not wrap to the starting address after the OTP address is at its maximum;
instead, the data will be indeterminate.
