The 2-Mbit flash products also provide excellent de-

sign solutions for Digital Cellular Phone and Tele-

communication switching applications requiring high

performance high density storage capability cou-

pled with modular software designs and a small

form factor package (x8-only bus) The 2-Mbit’s

blocking scheme allows for an easy segmentation of

the embedded code with 16 Kbytes of Hardware-

Protected Boot code 2 Main Blocks of program

code and 2 Parameter Blocks of 8 Kbytes each for
