I was pretty sure SRAM uses less power than DRAM. Some research shows it is true for 6T cells, but questionable on smaller 4T cells, depending on implementation

I was pretty sure SRAM uses less power than DRAM. Some research shows it is true for 6T cells, but questionable on smaller 4T cells, depending on implementation. So, if you can use ~6x the area of eDRAM, you can have almost no power draw SRAM.
