GENERAL DESCRIPTION
The MT28F322P3 is a high-performance, highdensity, nonvolatile memory solution that can significantly improve system performance. This new architecture features a two-memory-bank configuration that supports background operation with no latency.
A high-performance bus interface allows a fast page mode data transfer; a conventional asynchronous bus interface is provided as well.
FEATURES
• Flexible dual-bank architecture
Support for true concurrent operation with zero latency
Read bank a during program bank b and vice versa
Read bank a during erase bank b and vice versa
• Basic configuration:
Seventy-one erasable blocks
Bank a (8Mb for data storage)
Bank b (24Mb for program storage)
