Each piece of data is kept on a distinct battery in a form of Memory called DRAM. Because less tangible room is needed to keep the same quantity of data than if it were kept formally, this method of data storage in RAM is more effective. A DRAM chip can therefore store more data than an SRAM (static RAM) chip of equal capacity. However, DRAM consumes more power than SRAM because its batteries must be replenished frequently to maintain their charge.

Nevertheless, DRAM is the most prevalent form of memory found in personal computer systems because it can store more data than SRAM and is considerably less costly to produce. DRAM comes in a variety of forms, but the most popular one is synchronous DRAM SDRAM, a quicker variation of conventional DRAM. The majority of systems use this kind of memory as their primary system memory.

If you decide to update the SDRAM in your computer, examine the specifications to see if memory units need to be inserted in pairs. If so, replacing two units at once will be necessary, and they must be the same size (i.e. two 1GB SDRAM memory modules).
