Random Data Program

The RANDOM DATA PROGRAM sequence programs or replaces data in a page with existing

data. The random data program sequence is as follows:

• 06h (WRITE ENABLE)

• 84h/34h (PROGRAM LOAD RANDOM DATA)

• 10h (PROGRAM EXECUTE)

• 0Fh (GET FEATURE command to read the status)

Prior to performing a PROGRAM LOAD RANDOM DATA operation, a WRITE ENABLE(06h)

command must be issued to change the contents of the memory array. Following a WRITE

ENABLE (06) command, a PROGRAM LOAD RANDOM DATA (84h/34h) command must be

issued. This command consists of an 8-bit Op code, a 16-bit column address. New data is

loaded in the column address provided with the 12 bits. If the random data is not sequential,

then another PROGRAM LOAD RANDOM DATA (84h/34h) command must be issued with a

new column address. And the device is limited to one program data load per each a fixed length

of 8 byte section within a 2112 byte(page).

After the data is loaded, a PROGRAM EXECUTE(10h) command can be issued to start the

programming operation.
