To solve the problem, we need to understand the characteristics of a flash ROM and identify which option it is most similar to. Let's examine the options:
A: SRAM (Static Random Access Memory) - SRAM is a type of volatile memory that retains data as long as power is supplied to it. It does not match the characteristics of a flash ROM, which is a non-volatile memory that retains data even when power is removed. Therefore, option A is not the correct answer.
B: DRAM (Dynamic Random Access Memory) - DRAM is another type of volatile memory that requires constant refreshing to retain data. Similar to SRAM, it does not share the non-volatile characteristics of a flash ROM. Therefore, option B is also not the correct answer.
C: PROM (Programmable Read-Only Memory) - PROM is a type of non-volatile memory that can be programmed once to store data permanently. While PROM and flash ROM share the non-volatile aspect, there is a fundamental difference between them. Flash ROM allows for reprogramming or erasing of data, whereas PROM is programmed only once and cannot be changed. Therefore, option C is not the correct answer.
D: EPROM (Erasable Programmable Read-Only Memory) - EPROM is a type of non-volatile memory that can be erased and reprogrammed multiple times. Flash ROM shares this key characteristic with EPROM, as both allow for the alteration of stored data. Therefore, option D is the correct answer.
Based on the analysis above, the correct answer is D: EPROM.
