the real problem is that everybody keeps just going bigger with memory, meanwhile memory access time is only getting slower, not faster, instead of focusing efforts on speeding up processing power someone needs to get on top of that memory speed curve and push the limits a bit, if you could double your memory access speed you could exponentially increase the available address space for total memory because you could double-clock memory accesses. there are lots of smaller and single-purpose sdram chips that do this already, currently i’m using one because i’m designing an FPGA system with limited I/O pins and i’m sending video frames through ethernet from a submarine to a console. granted it’s much more feasible because my FPGA’s clocking at 50 MHz, so double-clocking the 133 MHz sdram isn’t a problem, but still…anyone who wants to set a market trend, there’s your place.
