Which type of memory is synchronous dynamic random access memory?

Synchronous dynamic random access memory (SDRAM) is categorized as volatile memory because it requires power to maintain the stored information. If the power is turned off, the data in SDRAM is lost. This characteristic of being dependent on constant power to retain information is what defines volatile memory. SDRAM operates in synchronization with the system clock, which enhances its efficiency and speed in data processing, but this does not change its inherent nature as volatile. In contrast, static RAM (which is another type of memory) retains data as long as power is supplied, but it is not synchronous or dynamic like SDRAM. Non-volatile memory types, such as flash memory and hard drives, retain information even when power is lost, which distinguishes them from SDRAM. Thus, understanding SDRAM's reliance on power clarifies why it is classified as volatile memory.
