The Intel StrataFlash® Synchronous Memory (K3/K18) product line adds a high performance
.Dburst-mode interface and other additional features to the Intel StrataFlash® memory family of
products. Just like its J3 counterpart, the K3/K18 device utilizes reliable and proven two-bit-per-
cell technology to deliver 2x the memory in 1x the space, offering high density flash at low cost.
wThis is Intel’s third generation MLC technology, manufactured on 0.18 µm lithography, making
it the most widely used and proven MLC product family on the market.
wK3/K18 is a 3-volt device (core), but it is available with 3-volt (K3) or 1.8-volt (K18) I/O
mvoltages. These devices are ideal for mainstream applications requiring large storage space for
w oboth code and data storage. Advanced system designs will benefit from the high performance
.cpage and burst modes for direct execution from the flash memory. Available in densities from 64
Mbit to 256 Mbit (32 Mbyte), the K3/K18 device is the highest density NOR-based flash
t4Ucomponent available today, just as it was when Intel introduced the original device in 1997.

est datasheet before finalizing a design.

2.6 Memory Map
The K3/K18 device array is divided into symmetrical blocks that are 64-Kword in size. A 64 Mbit
device contains 64 blocks, a 128 Mbit device contains 128 blocks and a 256 Mbit device contains
256 blocks. Flash cells within a block are organized by rows and columns. A block contains 512
rows by 128 words. The words on a row are divided into 16 eight-word groups. (See Figure 2.)
