If you are looking at something that is more DDR-like have a look at RLDRAM (Reduced Latency DRAM). I think Micron is about the only company still making the stuff. Generally speaking, all DRAM are optimized for burst-type operation and generally really struggle with random accesses or r-w / w-r operations. The controller is also a big factor in this. SSRAM is better in this regard but sustained throughput and clock frequencies are commonly far less than their dynamic cousins. Stephen
