Intel StrataFlash™ Memory Flash
Technology
Capitalizing on two-bit-per-cell technology, Intel StrataFlash™ memory products provide 2X the bits in 1X the
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.
By applying FlashFile™ memory family pinouts, Intel StrataFlash memory components allow easy design
migrations from existing 28F016SA/SV, 28F032SA, and Word-Wide FlashFile memory devices (28F160S5
and 28F320S5).
Intel StrataFlash memory components deliver a new generation of forward-compatible software support. By
using the Common Flash Interface (CFI) and the Scaleable 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, Intel StrataFlash memory provides the
highest levels of quality and reliability.
