Command
hexadecimal.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A20, DQ8-DQ14 and DQ15
are Don’t Care. DQ15A–1 is A–1 when BYTE is V
The maximum number of cycles in the command sequence is 68. N+1 is the number of bytes to be programmed during the Write to Buffer and
Program operation.
Each buffer has the same A4-A22 addresses. A0-A3 and DQ15A-1 are used to select a byte within the N+1 byte page.
The 6th cycle has to be issued N time. WBL scans the byte inside the page.
BA must be identical to the address loaded during the Write to buffer and Program 3rd and 4th cycles.
