Dram is made up of capacitors and transistors
WebJun 13, 2024 · In 1967, IBM filed for a patent on my single-transistor dynamic random access memory, which became known as DRAM. The patent (Fig. 1) was issued in 1968. In 1970, Intel built the first ... Web2 days ago · Because SRAM uses flip-flops, which can be made of up to 6 transistors, SRAM needs more transistors to store 1 bit than DRAM. If we compare, DRAM only uses a single transistor and capacitor. Thus, SRAM requires a higher number of transistors for the same amount of memory. All this increases the production cost.

But since the charge on the capacitor slowly leaks away, there will be additional circuit to periodically refresh the charge and keep the data intact. Hence, it is Dynamic. SRAM needs 6 transistors to store 1-bit data. DRAM needs only one transistor (and a capacitor) to …
WebDRAM: [noun] a type of RAM that must be continuously supplied with power and periodically rewritten in order to retain data — compare sram. Capacitor design. Up until the mid-1980s, the capacitors in DRAM cells were co-planar with the access transistor (they were constructed on the surface of the substrate), thus they were referred to as planar capacitors. The drive to increase both density and, to a lesser extent, performance, required denser designs.
