NON-VOLATILE MEMORY ROBUST START-UP USING ANALOG-TO-DIGITAL CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide a non-volatile memory that assures proper access.SOLUTION: In accordance with at least one embodiment, an onboard analog-to-digital converter (ADC) on a system-on-a-chip (SOC) is utilized to determine whether a charge pump output for a non-volatile memory (NVM) is correct or not. The SOC is directed to wait until the output is within an expected range before moving to the next step in a start-up procedure. If the maximum allowed start-up time is exceeded, an error signal is sent to the SOC such that the application can react to it.
