64K Byte Block Erase
The 64K-byte Block Erase instruction clears all bits in the
selected block to FFH. A Block Erase instruction applied to a
protected memory area will be ignored. Prior to any Write
operation, the Write Enable (WREN) instruction must be
executed. CE must remain active low for the duration of the any
command sequence. The Block Erase instruction is initiated by
executing an 8-bit command, D8H, followed by address bits [A
4K Byte Sector Erase
The Sector Erase instruction clears all bits in the selected sector
to FFH. A Sector Erase instruction applied to a protected memory
area will be ignored. Prior to any Write operation, the Write
Enable (WREN) instruction must be executed. CE must remain
active low for the duration of the any command sequence. The
Sector Erase instruction is initiated by executing an 8-bit
command, 20H, followed by address bits [A
