The world’s first x8 Octal interface for NAND Flash, Winbond’s OctalNAND Flash enables automotive and industrial manufacturers to provide code storage in high density without having to pay a premium for NOR Flash, a fast memory technology which scales poorly at densities above 512Mbits.

The first Winbond product to include the new interface, the 1Gbit W35N01JW, offers a maximum continuous Read throughput of 240MB/s, three times faster than the earlier high-performance W25N-JW QspiNAND Flash family.

Manufactured in Winbond’s proven 46nm Single Level Cell (SLC) NAND fabrication process, the W35N-JW OctalNAND Flash offers excellent data integrity and more than ten years’ data retention. It is specified to perform more than 100,000 Program/Erase cycles, providing the high level of endurance and reliability required in mission-critical automotive and industrial applications.
