HYPERBUS™ interface, 1.8V/3.0V

Interface overview

2.4.1.4

Embedded algorithms (EA)

Changing the nonvolatile data in the memory array requires a complex sequence of operations that are called

Embedded Algorithms (EA). The algorithms are managed entirely by the device’s internal EAC. The main

algorithms perform programming and erase of the main array data and the ASOs in HYPERBUS™. The host system

writes command codes to the flash device address space. The EAC receives the commands, performs all the

necessary steps to complete the command, and provides status information during the progress of an EA.

2.4.1.5

Advanced sector protection (ASP) management

ASP provides protection methods to disable or enable programming or erase operations in any or all sectors. The

EAC manages this protection to maintain data integrity.
