Working Principles

The CY14B256LA-SP25XI is based on flash memory technology. It utilizes a floating gate transistor structure to store and retrieve data. When writing data, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in threshold voltage represents the stored information. During read operations, the threshold voltage is measured to determine the stored data.
