Maxwell Technologies’ 29F0408 high-performance flash memory. 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 operation programs the 528-byte page in 250 µs 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 internal verify and margining of data. Even write-intensive systems 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.
These algorithms have been implemented in many mass storage 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.
About RAD-PAK® Technology
Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
