Numonyx™ StrataFlash® Cellular Memory (M18)
1.0
Introduction
Numonyx™ StrataFlash® Cellular Memory is the sixth generation Numonyx™
StrataFlash® memory with multi-level cell (MLC) technology. It provides high-
performance, low-power synchronous-burst read mode and asynchronous read mode
at 1.8 V. It features flexible, multi-partition read-while-program and read-while-erase
capability, enabling background programming or erasing in one partition
simultaneously with code execution or data reads in another partition. The eight
partitions allow flexibility for system designers to choose the size of the code and data
segments. The Numonyx™ StrataFlash® Cellular Memory is manufactured using Intel*
65 nm ETOX* X and 90 nm ETOX* IX process technology and is available in industry-
standard chip-scale packaging.
