Flash ROM is distinctive because it can be reprogrammed without changing chips. This capability allows for data to be written, erased, and rewritten without the need to physically replace the memory chip itself. This feature is particularly advantageous in situations where firmware updates or data changes are necessary, making it a flexible solution for many applications.

In contrast, many forms of ROM (Read-Only Memory) require the entire chip to be replaced to update or modify the data it contains. Flash ROM addresses this limitation, as it can retain data even when power is turned off, differing from options that state it can only hold information while powered. It is also designed to operate at speeds comparable to standard ROM, rather than exceeding those speeds significantly. Thus, the ability to be reprogrammed without the need for chip replacement is what truly sets Flash ROM apart in the realm of non-volatile memory technologies.
