MEMORY ARRAY ORGANIZATION
The memory array is made up of NAND structures
where 32 cells are connected in series.
The memory array is organized in blocks where
each block contains 64 pages. The array is split
into two areas, the main area and the spare area.
The main area of the array is used to store data
whereas the spare area is typically used to store
Error correction Codes, software flags or Bad
Block identification.
In x8 devices the pages are split into a 2048 Byte
main area and a spare area of 64 Bytes. In the x16
devices the pages are split into a 1,024 Word main
area and a 32 Word spare area. Refer to Figure
Bad Blocks
The NAND Flash 2112 Byte/ 1056 Word Page de-
vices may contain Bad Blocks, that is blocks that
contain one or more invalid bits whose reliability is
not guaranteed. Additional Bad Blocks may devel-
op during the lifetime of the device.
The Bad Block Information is written prior to ship-
ping (refer to Bad Block Management section for
more details).
Table 4. shows the minimum number of valid
blocks in each device. The values shown include
both the Bad Blocks that are present when the de-
vice is shipped and the Bad Blocks that could de-
velop later on.
These blocks need to be managed using Bad
Blocks Management, Block Replacement or Error
Correction Codes (refer to SOFTWARE ALGO-
RITHMS section).
