programming, or partially altered after an erase or lock-bit configuration. Therefore, block erase

Power Dissipation
When designing portable systems, designers must consider battery power consumption not only
during device operation, but also for data retention during system idle time. Flash memory’s
nonvolatility increases usable battery life because data is retained when system power is removed.
