What is Flash-EPROM memory?

Flash-EPROM (erasable programmable read-only memory) is a type of non-volatile memory, meaning this memory card retains data even when the power is switched off. As its name implies, a memory card with this type of memory can be erased and reprogrammed, so you can easily free up space as needed to make room for additional data.
