ESCRIPTION
:
Maxwell Technologies鈥?29F0408 high-performance flash mem-
ory. The 29F0408 is a 4M (4,194,304) x 8-bit NAND Flash
Memory with a spare 128K (131,072) x 8-bit. A program oper-
ation programs the 528-byte page in 250 碌 s and an erase
operation can be performed in 2 ms on an 8K-byte block. Data
within a page can be read out at 50 ns cycle time per byte.
The on-chip write controller automates all program and erase
functions, including pulse repetition, where required, and inter-
nal verify and margining of data. Even write-intensive systems
can take advantage of the 29F0408鈥檚 extended reliability of
1,000,000 program/erase cycles by providing either ECC
(Error Correction Code) or real time mapping-out algorithm.
These algorithms have been implemented in many mass stor-
age applications. The spare 16 bytes of a page combined with
the other 512 bytes can be utilized by system-level ECC. The
29F0408 is an optimum solution for large non-volatile storage
applications such as solid state storage, digital voice recorder,
digital still camera and other portable applications requiring
nonvolatility.

廬 packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. Capable of surviving in space environments, the
29F0408 is ideal for satellite, spacecraft, and space probe
missions. It is available with packaging and screening up to
Class S.
