MaxwellTechnologies’ 29F0408high-performanceflashmem-
ory. The 29F0408 is a 4M (4,194,304) x 8-bit NAND Flash
Memorywithaspare128K (131,072) x8-bit. Aprogramoper-
ation programs the 528-byte page in 250 μs and an erase
operationcanbeperformedin2msonan8K-byteblock.Data
within a page can be read out at 50 ns cycle time per byte.
Theon-chipwritecontrollerautomates allprogramanderase
functions,includingpulserepetition,whererequired,andinter-
nalverifyandmarginingofdata.Evenwrite-intensivesystems
can take advantage of the 29F0408’s extended reliability of
1,000,000 program/erase cycles by providing either ECC
(Error Correction Code) or real time mapping-out algorithm

ogy incorporates radiation shielding in the mcrocircuit pack-
age. Capable of surviving in space environments, the
29F0408 is ideal for satellite, spacecraft, and space probe
mssions. It is available with packaging and screening up to
ClassS.
