Sector-Erase
The Sector-Erase instruction clears all bits in the selected 4
KByte 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
Block-Erase
The Block-Erase instruction clears all bits in the selected 32
KByte 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
any command sequence. The Block-Erase instruction is
initiated by executing an 8-bit command, 52H or D8H, fol-
lowed by address bits [A
