Abstract
In accordance with at least one embodiment, a clock counter on a system (for example, a system-on-a-chip (SOC) or other system) is utilized to count a number of a clock edges of a memory clock within a predefined time based on a predetermined system clock frequency and, therefore, to determine whether the memory clock for a memory array (for example, a non-volatile memory (NVM) array or other memory array) is correct or not. The system is directed to wait until the count 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 system such that the application can react to it.
