Capitalizing on two-bit-per-cell technology, 5 Volt Intel StrataFlash® memory products provide 2Xthe bits
in 1Xthe space. Offered in 64-Mbit (8-Mbyte) and 32-Mbit (4-Mbyte) densities, Intel StrataFlash memory
devices are the first to bring reliable, two-bit-per-cell storage technology to the flash market.
Intel StrataFlash memory benefits include: more density in less space, lowest cost-per-bit NOR devices,
support for code and data storage, and easy migration to future devices.
Using the same NOR-based ETOX™ technology as Intel’s one-bit-per-cell products, Intel StrataFlash
memory devices take advantage of 400 million units of manufacturing experience since 1988. As a result,
Intel StrataFlash components are ideal for code or data applications where high density and low cost are
required. Examples include networking, telecommunications, audio recording, and digital imaging.
Intel StrataFlash memory components deliver a new generation of forward-compatible software support.
By using the Common Flash Interface (CFI) and the Scalable Command Set (SCS), customers can take
advantage of density upgrades and optimized write capabilities of future Intel StrataFlash memory devices.
Manufactured on Intel’s 0.4 micron ETOX™ V process technology and Intel’s 0.25 micron ETOX VI
process technology, 5 Volt Intel StrataFlash memory provides the highest levels of quality and reliability.
