The M29W640G has an extra block, the extended block, of 128 words in x16 mode or of
256 bytes in x8 mode that can be accessed using a dedicated command. The extended
block can be protected and so is useful for storing security information. However the
protection is not reversible, once protected the protection cannot be undone.
The M29W640GT, M29W640GB, M29W640GH and M29W640GL, are offered in TSOP48
(12 x 20 mm), TSOP56 (14 x 20 mm), TFBGA48 (6 x 8 mm, 0.8 mm pitch), and TBGA64
(10 x 13 mm, 1 mm pitch) packages.
The memory is delivered with all the bits erased (set to ‘1’).
