Something I don't understand is why SRAM is more expensive than SDRAM. Is it just the manufacturing volumes and/or manufacturing yield, or are there architectural differences that make SRAM more expensive?
- cesarb 9y agoEach "bit" in SRAM is bigger than each "bit" in DRAM. Typical SRAM uses six transistors for each "bit", while typical DRAM uses one transistor and one capacitor. Bigger chips means less chips per wafer, and a larger chance for a chip to have a manufacturing defect.
