WebPrice. SRAM is much more expensive than DRAM. A gigabyte of SRAM cache costs around $5000, while a gigabyte of DRAM costs $20-$75. Since SRAM uses flip-flops, which can be made of up to 6 transistors, SRAM needs more transistors to store 1 bit than DRAM does, which only uses a single transistor and capacitor.
