What is flash memory similar to in terms of its ability to be written?

Flash memory is similar to ROM in terms of its ability to be written because both can retain data without power. However, while traditional ROM can typically only be written once during the manufacturing process, flash memory allows for multiple read and write cycles. This characteristic makes flash memory a non-volatile storage option, meaning it can hold onto data even when the power is turned off, similar to how ROM operates in that respect. Flash memory is frequently used in devices requiring fast access to data, as it is typically faster than traditional hard drives. It is noteworthy that while SSDs (solid-state drives) utilize flash memory, the relationship primarily lies in their underlying technology, and the question focuses on the writing capabilities rather than the type of device.
