PDC's 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 µ 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 internal verify and margining of data.
Even write-intensive systems can take advantage of the 29F0408 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.
PDC's patented RAD-PAK packaging technology incorporates radiation shielding in the microcircuit package. 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.
