Flex-OneNAND™
Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array using a NOR Flash interface. This on-chip integration enables system designers to reduce external system logic and use high-density NAND Flash in applications that would otherwise have to use more NOR components.
Flex-OneNAND enables users to configure to partition it into SLC and MLC areas in more flexible way. While MLC area of Flex-OneNAND can be used to store data that require low reliability and high density, SLC area of Flex-OneNAND to store data that need high reliability and high performance. Flex-OneNAND can let users take advantage of storing these two different types of data into one chip, which is making Flex-OneNAND more cost- and space-effective.
